I like ur attitude though, u are determined to solve what is happening. . keep us posted. I was hopeing that you wouldhave ordered a new striker spring while u were at it, just to know for yourself that all thingin the striker channel now are new.. U just eliminating all the possabilities when u do that stuff..
I'm having pretty much the same problems with my P45, I ordered 2 sets of springs as well, I'll have them in this weekend.Quote:

IMHO the 45ACP is one of the easiest rounds to handload for as far as dimensions (OAL, etc...) and you really have to try to make them unshootable.
I'm beginning to believe it's the relationship between headspace and firing pin protrusion, but I'm working with my P45 to eliminate everything else in the meantime.
Hi Charlie98. Last night I took a small jewelers file to the shoulder of the firing pin and then polished the shoulder and tapered end of the firing pin with a kratex Dremel tool. As I measure it, the striker now extends another .005", which puts it about .029" - .030" from the breach face. I also replaced the striker and recoil springs with new factory springs.
I went to the range and fired 58 factory rounds, all of which fired. This was Winchester White box 230 grain, Blazed Aluminum Cased 203 grain, Remington Golden Saber 230 grain and Hornady 185 grain Critical Defense ammo. Every round fired. I then fired 66 rounds of my reloads, from the same lot that didn't work last time, all but one fired. I really think it didn't fire because the slide was not quite to full battery. It fired when I ran the slide part way back to cock the striker, and then ran the slide all the way forward.
I think the extra .005" fixed the problem. I'm not going to file it any further.
I dropped all new springs in my P45, it fired 100% with factory ammo and about 80% with my standard reload... light at the end of the tunnel, perhaps.
I still think there is a issue with the firing pin protrusion, I may wind up polishing down the striker shoulder and see how that does.

Did you get any comment from them about anything they may have done relating to this issue?
I have had no issues of FTFire with my first P45, bought shortly after these weapons were available for purchase. I have not checked to find out the manufacture date of the second used one. Since I use (or intend to use) this weapon for personal protection, it's imperative for it to work everytime the trigger is pulled. I have personal experience with C&S with other handguns, all revolvers. I am very hopeful that they can sort out all/any issues with my P45 and return it to me fully functional. I would appreciate any comments or thoughts you may have about the service you received from them on your Kahr. If you wish to make these off line, let me know and I'll provide contact info, or you can do the same and I'll get in touch. Thanks very much for any help you can give.
So long ... Pudge

My P.45 also has light strikes. Some times The chambered round that didn't fire will stick and I can hardly get it out. Once could tell the slide had'nt closed and hit it on back and it fired. Have tired 6 differant loads and all will do this. (factory) After having many problems with a P.380 I got rid of it. I have a PM9 that I have worked with a lot and think its reliable but still don't trust it 100%. Can't believe I was stupid enough to buy the P.45. Guess I throught that one out of three would work. Great feel, trigger, and acc But not much good if they not go bang. Spent enough on ammo to buy another pistol.
I've owned four Kahrs ... two P45s, a CW9, and a P380. All but one P45 were bought new. All except the used P45 have worked very well after the requisite breakin period recommended by Kahr. The new 45 and the new 9 had very few issues even during the breakin period. The P380 took a bit longer to get past breakin issues, but since that time has funtioned properly and I like it very well. Having bought the second P45 used, I have no idea what the previous owner may have done to it or had done to it. It does not appear to have fired many rounds, and I only have the FTFire with certain brands of ammo, specifically most often with S&B ammo. I have had no FTFs with premium ammo, just FMJ practice ammo. There is a definite difference in the primer strike of the used P45 and the one I bought new. I like the Kahrs very much, but I've gotta resolve the FTFs with this last one or it's not worth much!
