I just got a Kimber 1911 in 10mm. It came with 6 WC mags and a Kimber original. Supposedly it has a 22 lb recoil spring and another 20 lb in the box. The issue is that sometimes either the cartridge will get started in the chamber and hang up, or the slide won’t go into full battery. This happens it seems without provocation with all the mags and several different styles of bullets. Does anyone have any theories on a remedy? I really want to like this gun, as it is scary accurate, and hope for a simple fix. The gun is used, but maybe just needs more of a break in period. The previous owner said it only has about 500 rounds through it. Thoughts OSA? Thanks.
