I purchased a SW1911PD (no box or papers) with the intent of putting on my Colt 22 conversion, that I currently use on a Colt Government. When I got it installed, I could not pull the trigger. The only difference between the PD and my other 1911 is in the below picture. What is that part?

Firing pin safety

Looks to be a part of the firing-pin safety. The S&W design is operated by the grip safety. Does the trigger operate when the center-fire upper is mounted and the grip safety is disengaged?

When I first got the gun, I sent 200 rounds down range, with the original slide, with no problems. I can also put the trigger, with no slide installed.

You are correct. It is a firing pin safety. I found this thread.

Don't know what I am going to do now. I got the SW1911PD to use the 22 on.

My Colt was build in 1928, so no firing pin safety. My other SW1911 E-Series does not have it either.

Thats unfortunate. I was one of the members saying that a Colt .22 Conversion Unit will work on a S&W when you were asking originally. I've not seen that firing pin safety on a S&W before and as you can see my SW1911PC doesn't have one either.

The PD is a very nice shooter, so all is not lost. I will just put the 22 on my E-Series, and keep an eye out for something else.

Do you know the year your PD was built? Also, I see you are using a shock-buffer. Is that because of the Alloy frame?

My pistol is from the Performance Centre and its a full size all stainless pistol. I use the shock buffers on all my 1911's. Cheap insurance in my mind. We can't carry up here so I have no reliability concerns using them, although it's been 100% reliable with them.

Is that frame in the white? In any case, it looks nice. The softness of the factory finish was a minor nuisance as I was using kydex holsters at the time I puchased mine. } -;

[ed. Ah ... NVM ... steel, so yes, it’s in the white.]

Since you didnt recognize it ...

Since you didnt recognize it, you’ve likely not previously re-assembled a 1911-pattern with a FPS. And I’ve certainly re-assembled 1911-pattern pistols such that the FPS would not disengage; taken it back apart and, paying more attention, re-assembled it correctly as indicated by the action now working. That’d be my -guess- here. Never used a Colts’ .22 conversion ... but lots of other .22 conversions. So it’s -possible- there’s an incompatibility with the FPS ... but I’d be pretty surprised.

S&W has given me owner’s manuals for the asking. If they’ve had a policy change, it’s likely still worthwhile to get one. Ah ha! Is your S&W a government? Or a commander? That model I understand to be a commander ... and this might explain an incompatibility:

It is a government. I will examine the 22 slide and the PD Slide, and look for the differences. I assume the PD will have a firing pin plunger in the slide, for the upper sear to press on.
