I have a Colt LWOM that I purchased used twenty years ago.It was stock except the stocks were swapped out for Pachmayrs.I took it to the range and inside 50 rounds the gun stopped cold.The front recoil spring plug was now somewhere down range in pieces.The flimsy barrel bushing was tweaked and hard to open the gun,a little rubber mallet took care of that.
The gun sat for a year or so before reading(No INTERNET) some magazine articles on curing the OM woes,WTF were Colt engineers thinking??That little “bump” of metal was the retaining tab?These guys must have been related to the Titanic build team.The barrel bushing was equally thin and weak.Never cared for the dual recoil spring system.
Ed Brown made(no longer) a SS reverse recoil spring plug,easily fitted by hand with a file and micrometer measurements.I then fitted a Kings SS barrel bushing,very heavy duty unit.Wolff makes replacement recoil springs in 22(factory) and 24 lbs, I stuck with the factory weight.
The gun ran fine except occasionally on the last shot the slide would not lock back.The slide velocity on these shorty .45s is really high and the mag springs cannot keep up to trip the hold open(slide top).These are with factory Colt 6 rounders.I don’t run the 7 rounders due to them using a Devel type followers that is prone to gouging alloy frames.I have yet to swap mag-springs to see if they give the extra power to catch up to the fast recoiling slide.
CHANGE RECOIL SPRINGS OFTEN!!EVERY 500 ROUNDS!
Positives:
The gun comes with adequate fixed sights.The trigger was “decent” for social purposes,5 lbs fairly smooth and only a hint of creep.
The Pachmayers are nice,I normally don’t like Pachys on autos cause they are thick,but these are thin and wrap around.
My gun feeds ball and Federal HS no problem(old and new style)The HS do not beat up the alloy feed ramp on my gun.
Accuracy is fine for close range personal communication,its not a bullseye gun.
Very thin,light and compact.Recoil is easily managed and I do not consider the .45acp a brute,slide cycling is fast.
The gun is a good for carrying alot and shooting a little.
If your Officers Model is bone stock,replace the recoil spring plug,barrel bushing and recoil spring system.The factory recoil spring plug will break eventually.
