yessir, good info on the
Gun Guides' but as we've mentioned in other posts, it's when things start to "fail"...accuracy, spitting (blow by), misfires (also covers the cylinder moving forward and possibly rubbing agianst the rear of the barrel), failure to lock-up on each chamber,not "throwing by",etc., then you must look into the the causes...........if you are loading "hot ammo", learn to 'read your empty cases, as well as extraction, when you clean the gun, look at the throats (both the cylinders chambers, as well as the forcing cone)....look for cracks and erosion...........I do not recall seeing any "worn out" GP100's...yes,like anything else ,seen misuse, abuse, and wear.............
