I tried shooting my 1911 .22LR yesterday and upon doing that It wasn’t shooting. I know the bullets entering the chamber wasn’t the issue , I tried shooting it by clocking back the hammer and letting go and it shot. I’m new into 1911’s and have no idea what could be the issue. Would not having a thumb safety be the issue on why the gun wont shoot using the trigger?

When the slide is racked, as in loading the gun, the hammer does not remain cocked, it follows the slide?
If so, I'd be looking at the sear spring, to see if it's properly engaging the sear and disconnector.

A 1911 thumb safety is not a drop in part, it requires careful fitting. If you do just happen to get a thumb safety that fits and works out of the bag, you better get a helicopter ride to the nearest casino before your luck runs out.

The Browning 1911 22 is a smaller version of the 1911. Full size 1911 parts wont fit it. I don't know if Browning sells parts for those. I know sights are unobtainable. You may have to send it back to Browning.

They do not sell parts for it.
It will have to go back for repairs.

MY Browning 1911-22 has a thumb safety.
No idea what the OP doesn't have one.

I don't intend any offense, but you're new, and we don't know your experience level. Are you aware the 1911 is a single action pistol and with the hammer down, pulling the trigger won't cock the hammer.

It still doesn't explain why it doesn't have a thumb safety.

I find that statement surprising. In the original acceptance trials of the 1911 a bunch were disassembled and guns re-assembled from parts taken at random from the box of parts. All of them went together and functioned. If a safety doesn't fit and work, it's out of spec, or perhaps the frame is.

The Springfield Armory put an end to hand fitting individual parts about the time of the Civil War. The mass-production technology they pioneered helped fuel the Second Industrial Revolution, and heavily influenced Colt, S&W, and many other arms and machine makers.

First the OP's gun is the Browning 22 LR version. Smaller than a standard 1911.

GI spec parts were designed with generous tolerances to allow such mix and match. Even at that it did not always work. I know that both from anecdotal reports from others in the military (some of them family members) and from my own experience while in service and later.

Otherwise, there are so many manufacturers of parts and conplete guns, almost none of which comply with the originally spec'd GI tolerances, almost all of which have their own specifications with varying degrees of compliance with same, that anything dropping in without fitting is a miracle. Add to that the modern demands for accuracy, trigger quality, etc, that all require extra precise fitting work and it become a moot point.

GI spec hammer hooks were .030". You will not find a modern 1911 with hooks at that dimension. The standard when doing a trigger job is to start with .020" hooks and many go down from there. GI sears did not have a relief cut/escape angle while almost all modern sears will. GI hammer and sear allows enough "forgiveness" that a thumb safety that does not completely prevent movement of the sear is usually workable in that setting. Try that with modern hammer/sears and fitting techniques and you will end up with a very dangerous situation.
