I was changing my rear sight and lost the spring. Can someone tell me what it is for? Can I shoot the gun this way. I will call smith on monday and get another one comming.

Thanks for you help

The spring holds pressure on the firing pin safety, to hold it down. It could potentially be unsafe to shoot the gun without the spring. The firing pin safety blocks the firing pin from hitting the primer unless the trigger is pulled. With the spring missing, the firing pin might not be not blocked. You need to replace the spring before you shoot it. There is also a little flat cover that goes over the spring. Do you have that?

Yeah, every part of the gun has a function. I won't fire it with a single missing piece.

If you do have to send the gun, send only the slide, it is not a regulated item and is far cheaper to ship. Have Smith send the part directly back to you as well.

The springs are available now, the part number is 27749 and is the same for all the M&Ps, full size or compact. I did the same thing and modified a Glock spring that works. But only used this setup to check the new sights I put on. I will not carry the gun until I get the factotry springs. I ordered a few because eventaully I will be changing all the sights on my M&Ps. Anyway, call Smith and order a few. They are less than 2 dollars and it's probably a good spare part to have on hand.
