Went to the range yesterday with my SR1911 and P345 in tow. This stuff consistently would not load into my SR1911 but worked 99% of the time in my P345. I bought it at a gun shop liquidation auction at a decent price about $13 a box. The 1911 has never ever been finicky about what I fed her. I'll have to check OAL with calipers to see how it compares to other 45 ammo I have. Unfortunately I didn't have a different brand with me to see if it was the ammo. I've used this brand in 22LR with no issues.
