Recently bought a new to me black k40 SN: DL04XX. Cleaned and lubricated it and it appeared to be practically unfired. I love the fit and feel of this little gun and need help to make it work dependably.
I shot 50 rounds of Federal 180 grain HST JHP using both 6 round magazines. Several fail to feed with the round nose diving slightly with the tip of the round in the mag well and the brass head on the breech face. Also a few fail to feed where the gun went into battery without a chambering a round.
I cleaned and lubed and put another 100 rounds of the same ammo through it with similar results.
I read the Kahr prep posts and tested the magazines as directed, they were hanging up, so I polished the right side of the magazine followers, cleaned and lubricated the weapon as indicated and put another 50 rounds down range. Only one FTF with the round hanging up on the feed ramp. However there were numerous failure to feed where the gun cycles and goes into battery without stripping or chambering a round. Click.
I carry an HK P2000 on duty and have shot semi autos for 30 years. I don’t think I am limp wristing. In fact I have intentionally tried to limp wrist during the first 100 rounds and it cycled fine, the FTF were when I maintained a good grip. Also, I am not engaging the slide lock with my off hand, although the nose of the round comes close to the slide lock it isnt touching. Mag springs are in properly, with the coil angled up toward the front of the magazine.
Any other suggestions on what could be the issue. I don’t want to try another brand of ammo. I have access to the 180 grain Federal which is why I bought the .40 in the first place.
Thanks for your help, appreciate this forum.
