It's my new Colt Lightweight Commander in .45. I've got 716 rounds through it now. The issues I had with feeding before are gone. It runs like a champ now. I did get rid of the shockbuff and am not using it. I may put it back in at some point in the future, but I want to make sure that it works perfectly before I alter it. I only have one issue now. I have a bunch of semi-wadcutter reloads I'm using right now. The situation is with the slide locked back, I insert a fresh mag of SWCs, and drop the slide. The round will start to get into the chamber and jam up. Usually if I pull back on the slide a bit and let go it'll go in just fine from there. It will not jam again for the rest of the mag. No problems during normal firing, just when loading up the first round. Since it runs fine with all ball and JHP rounds I've tried, and it runs fine during normal shooting I'm not worried about it, but I am curious as to what it might be. |

Are you using the slide stop or are you sling-shotting it? I have had SWC rounds where they weren't seated quite deep enough so the shoulder would hit the rifling causing the round to not seat all the way. If I used sling shot method it usually would chamber the round, sometimes it would take two times. Try using the slingshot method or try seating your reloads a little deeper provided that it is safe to do so. |
The reloads are definitely seated high -- We went with this to help decrease pressure and make them softer shooting. And slingshot method works, but I wasn't using it  .So it's probably just my ammo then, cause it sounds like you experienced what I'm seeing. I just though it was weird that it would work during normal firing, but not on the first hand-loaded round. |

From your description it is a classic "3-point jam" Not likely to be related to high seated ammo........... at least not if your description is accurate. You say "The round will start to get into the chamber and jam up." If the round is "just" starting to go into the chamber it certainly is not deep enough yet for the high seated bullet to hit the barrel's rifling. So why does using the sligshot method work .....simple........ you are giving the Slide much more inertia to Jam the bullet into place. Simply installing a stronger recoil spring will give you the impression all is fine, because the 3-point jam will seemly go away for awhile. If it were my pistol ......... I would carefully check for bullet "set-back" after it loads some hardball ammo without a crimp. If you measure any set-back........then the pistol is not feeding correctly.......even though it will function most of the time. Once the 3-point Jam is properly corrected ...... the difference in loading will be like night and day. Your pistol will "feel" as if there are NO bullets in the magazine as you work the slide. You will be amazed at the feel and the difference. JF. |
Genius, eh?

Check your extractor tension, the hook length and angle, and polish quality. You may have too much tension, a burr on the extractor, or the hook is hitting the web of the case causing too much tension. 45's don't require a lot of tension. If this is a stock pistol, it is usually a polish issue (not Polish, but polish...) Also, is the pistol throated for SWC's? If not, it will jam the way you described.
