Apart for cleaning and the first job. Lots of touring the innerweb and it seems no body actually took 10 minutes to figure out how to "gunsmith" the oft offensive "magazine-out-action-locked" component illustrated in the upper left corner. Mostly folks are searching for info on what size washers to buy and drill out and thin up or they're spending $20 + Shipping for an aftermarket part to delete the magazine disconnect. I'm saving my money for Beer and RimFire ammo for New Years Eve by investing 10 minutes in looking over the part and making 2 simple modifications....(The mods the aftermarket part suppliers make lotsa money on.)
Cause $20 or so gets me 50 odd cheep shells to make noise with and a whole buncha Pearl Light or Mickies Wide Mouth Malt Likker.

I simply cut off the dog tail and polished the edges. (Left side of photo.)
Then i flattened the underside of the mag disconnect, (Right side of photo ), shown here almost done, just having a smoke before I finish flattening it out and polishing the new underside surface on the stone.

Final reassembly gave me a chance to loose the ambi safety.....Might have to pass it along to a functionally misguided member of the doodads and gadgets generation.
Function tests proved a success, including snapping primers on debulleted ammunition (cause its dark and cold now and the outlaws are still on stand trying to get on the big game before time runs out this season, don't wanna disturb them in their quest.)
So, mag disconnect delete completed. No worries and I still have my beer and ammo money.

It almost fits my favorite home made (and only one I have) 1911 Officers ACP holster.
I think i know what the next hack will be.....among the several others I'm pondering.
Prolly should shoot it some. Always good to shoot em a bit when they're new.....

Looking fine at 4" of barrel and a double crown. Flat face almost to the edge and then deeper at 11 degrees with a smaller cutter. The outer edge rounded over to ease the sharp edge. A touch of perma blue darkens up the muzzle.

And now it fits my ambidextrous holster. As heavy as this gun is I 'spect it'll carry just like an Officers ACP, solid.
(PS...full size 1911 grips can be fitted, perhaps a nice slab of afzelia xylay in the near future. )

Finally got it out on steel today.
Nicely, the sights were right on for initial work at 3 to 10 yards. Don't really like the front sight but it'll do for now. Florescent beads are great but I usually break them so....
Fed her about 150 rounds total from Federal Lightning, Federal Auto Match and the Winchester Super X hollow point. Everything went in and out at 11 +1 and no issues. Mag mods were to add one round of capacity and round over the ears to prevent stove pipes.
Trigger breaks at a good safe carry weight of 4 lbs 15 ounces. It breaks pretty clean but there is a yard of take up that you only notice if trying to prep the break. When shooting double and triple taps, its unnoticeable. About the only good way to reduce the take up (on factory parts) is to lower the hammer hook and even then, a lot of the slop is probably in the trigger bar. I'll leave it alone. Its reliable and easy to shoot as is and I'm not interested in match/group shooting anyway.
Barrel at 4 inches is reliable and still enough length to sight well and naturally, quickly. A bead of some sort would be much better for these eyes. Probably could have gone 3.5 inches of barrel and retained reliability with these somewhat faster shells, but, happy here. Should eat just about anything I can lay hand to with the shortened barrel....(I see ruger coming out with a 22/45 that has an even shorter barrel than this and they are saying it runs fine with or without a can installed. I don't get the whole can thing but then, lotsa folks don't get why I have an 85 year old sedan for a daily driver.)
Holster fit is nice and it doesn't jug my side like the 1911 did....could be the gun, could be weight loss on my part. But, happy enough that I'll carry it and use it.
Now to find those afzelia xylay grips....

Update....in a never ending quest not to purchase aftermarket parts. About 1000 rounds down range now. Perfect function and I'm quite pleased. Moving back one step with each successful ring of the steel, I find the trigger allows me to be consistent on a vertical 3x8 steel rectangle to about 30 yards. After that, the long take up interferes with staging the pull and most misses are off the left side of the swinger.
So.....I'll reduce the take up, free.

First step is disassembly and removal of the Factory Aluminum trigger. Jigged up on the drill press, a 1/16" hole is drilled about .250" deep just below the trigger pin and no worries, the new spacer pin will bear on the steel frame mounting block rather than any portion of the plastic frame.
Afterwards, a suitable length of the drill bit is cut off, extra long, to begin fitting.

The section of drill rod is inserted in the newly drilled hole and everything reassembled. Disassembly and reassembly is repeated with swipes of a medium stone across the face of the pin until such time as the weapon will reliably reset the trigger when "FULLY" assembled. (Note, on this particular model, the hammer would reset without the action in place and fail to reset once the upper was installed, as such, my initial stopping point of .040" protrusion was too long for reliability.) I wound up with .036" protrusion from the face of the trigger allowing reliable reset of the trigger with the upper installed. Upon achieving functional reliability, the pin was bonded in place with 609 sauce and reassembled/function checked again.....

Looking at the assembly through the trigger guard, the new pin is just visible below the mold parting line. (The factory disconnector, sear and hammer were all polished bright and lightly greased at contact points yielding a reliable 4 lb 2 oz trigger pull.)
There is about a 90%+ reduction in take up now. Only the slightest movement is felt now (where before there was a ton of mushy take up and no clear break point) and the stop point of the take up is positive enough to allow staging the break over. Things should go better on the range and hopefully I can commence hitting that steel swinger from 30 yards on back to 50 yards now.

For this field carry gun, the sub 5 lb trigger pull is desirable and quite usable. Getting the over-travel down to a minimum makes for a much better feel. I am more pleased than I was previously, and was very pleased then anyway. Besides, it didn't cost any money, just some basic gunsmithing. While I'm sure its not as nice as a "purchased" trigger job, but it is quite a bit better than what the factory provided. For me the juice is worth the squeeze.

This is amazing. Great job, and you still have your beer money.

Figured this was a good time for a reliability update. Two types of ammunition are regularly used (Federal Automatch 40g 1200 fps and Federal 510 champion, 40g, 1240 fps.)
The barrel was trimmed to 4 inches, mags modded to 11 rounds for 11+1 capacity.
Both ammo function the weapon reliably. At about 4oo rounds without cleaning, the gun is dirty and dry enough that Federal AutoMatch will not reliably eject when 10 or more rounds are loaded in the magazine. At that point, i either pull the bolt and clean, lightly grease or simply switch to Federal Champion 510 (I have not found a round count with attendant gunk build up that will result in the failure to reliably function the weapon when using the Federal Champion 510.)
As such, and given the action retains its heavier rated recoil spring, I'm quite pleased with the short barrel. Carry is easier and lighter, accuracy and reliability are super.

I always admire you for these threads. Now what really shows me you’re a man of class is the appreciation for Mickeys.
