Replacement hammer question

[Khurrle]

So as many of you know. The first weekend I had my 15-22 the J pin in the hammer sheered off and after an email to S&W there was a replacement hammer on its way to me.

I replaced the hammer already wih a DPMS hammer since I heard that the S&W hammers are prone to break in the same way. Somewhat of a known issue I guess.

Anyway, I received the hammer today with a new set of pins and was surprised to find that this hammer doesn't even have the I pin in it and the pins are exactly the same as what I have currently.

Is this expected and is the .22 low enough recoil that the pins shouldn't try to drift? Needless to say I left the DPMS hammer and original pins. I'm just curious if I got the standard issue part or they sent me a bum part.

Here's a pic for anyone interested.

The hammer has to have the J spring, otherwise the hammer pin will
walk out, there is nothing else to keep it in place.

Exactly! OP, save the pins and throw the hammer in the trash.

Just chuck everything and get a set of KNS 15-22 non-rotating locking pins and you are set no matter what trigger you put in.

Yeah I thought this was a bunk part. But since I have the DPMS one in there I was just going to keep this one as a back up. I'll still keep it as a JIC thing and I'll definitely hold onto the pins.
