I know this has been discussed to death in these forums, and I've read most of the threads. I've tried a lot of things and I simply can not stop shooting left with my P30 and P30SK. It's slight, but it is consistent. It isn't very pronounced at 10 yards, but at 20-25 yards it become an issue.
I've mostly shot 1911s and their clones. I'm a pretty experienced pistol shooter. At 30 feet, I can empty a mag slowly, and 10-15 rounds all touch - they're just 1-2 inches left. At 25 yards I have a 3-4 inch group - but also 3-4 inches left.
I currently own a Sig P938 and a Glock 17, and I shoot true with both of them. I have a laser bore sight and it's not the guns.
I've adjusted backstraps, I've tried different grips, I've tried putting in snap caps. I'm not anticipating, and I don't seem to move the gun left when I do dry-fire practice.
I have both a P30S and a P30SKS, both in variant 3. It is actually *less* pronounced with the P30SK. Neither gun are "new" - I've had them for about 2 months and have 1-2k rounds through each of them.
Has anyone struggled with this before? Is it the trigger? What do I need to focus on to correct this? It is driving me MAD.
