Hammer Spur / Main Spring PROBLEM!
I am new to the forum, and needing help.
I have an older Pro Tactical II Special Edition bought used a year ago. The gun has ran pretty decent, but I wanted to "tune it up" with new springs and such. I've ran several hundred rounds through it, had a couple of FTE issues and a couple of times where it felt like the grip safety wasn't working and it failed to fire. I had to bump it and really pull on the trigger to get it to fire. Then it ran ok. Seemed to happen during rapid fire most often. Not good at all on a EDC personal defense gun. And it hits so sweet, I had to fix it.
So I ordered a spring set and an extractor and took the gun apart. Put it back together and it ran fine. But I reviewed a few vids on U Tube and looked at some diagrams and there was a problem.
There was no Main spring retention pin in the Main spring housing assembly. The Main spring and cap protruded out from the top of the housing assembly. This set off some concerns obviously, although it went back together and fired ok.
So I ordered the Main spring retention pin, disassembled it again, reassembled according to the vids and the diagrams and no good!
The hammer hung loose. It seems like the hammer spur is too short to fully seat into the Main spring housing properly. Now, I took it apart, reassembled without the pin with the Main spring protruding, which I now know to be incorrect and it works. But I am not happy. This is not right.
I called Kimber tech and they agree I have a problem. So I figure somebody somewhere prior to me has done some Jŗck leg service. Most likely put a incorrect hammer and spur assembly in it. Who knows, maybe a hammer assembly for a compact? And managed to field engineer it by incorrectly assembling it. When pulling the hammer back when incorrectly assembled, there's significant pressure, and I've never had a FTF with a light hammer strike.
Anyone able to confirm or deny? Anyone have the dimensions of the hammer spur? Kimber was not able to provide this info.
This is as best I can tell a Commander size, with a four inch barrel and a full size grip. The spur looks to be about a quarter inch short, roughly. That's why I wondered about a hammer assembly for a compact with a four inch barrel and short grip. I really don't know, I guess I will order a new hammer assembly but wanted to check here first. The Main spring housing assembly appears aftermarket as it is metal not plastic.
Sorry for the long post, but wanted to make sure I gave all pertinent info. Wish I had measured the hammer spur before I put it back together though. Pic attached shows Main spring housing assembly components and dimensions. Assuming I have to buy a new hammer assembly, any preferences? I tend to Wilson Combat.
Thanks in advance for any help offered.
I took her down again and measured the strut. 2.2 inches. Looks correct. Now I'm really confused.
