Tisas 9mm GI type pistol. Had it for awhile. Goal was keeping as many parts factory while getting ot to where I like this format 1911. The accuracy wasn’t as consistent or tight as I desire. Accuracy doesn’t need to be fit match barrel tight groups but a group of bullet impacts a little more aseociated was desireable.
So removing the link, doing some math, cutting a shim for the rear barrel upper locking groove. Cutting the shim just a squeak wider than the groove swages and keeps the shim where it belongs. This is a chrome coated barrel so silver solder would probably be ineffective.
Net result
- upper lug lockup. .042”;
- link about .002” long but allow pin contact on lower lugs in full battery position;
- zero vertical clearance when the slide is pulled back about .010”.
