Howdy folks,
Like most 75B owners have stated, many of us have far more than the "magic 1500 rounds" through our pistols already, without any issues.
I have two 75Bs in 40, and an SP-01 in 9. All three pistols have never had a "target/light" load fired through them. I don't shoot competition, so I see no need to fire light or target loads. These are carry pistols for me, and as such every round that goes downrange is either a factory JHP or a reload that equates to my factory/carry rounds.
One of my 75Bs has had well over 6000 rounds through it now, of hot and very hot loads (two different calibers), and what amazes me the most is it looks internally and externally as if it has not fired more than a few mags so far. That is the only issue that surprises me at all with the strength and quality of the CZ pistols. My other two pistols have nearly that number of rounds through each of them, also of carry/carry like reloads.
So if there was any basis at all for the "magic 1500" mark, I should have already had to replace several slide lock levers to date. IF this has ever happened, at it may well have for a few folks, I strongly suspect they began to change a lot of springs and then fired rounds not well suited to that combo installed in their pistols. But I am sure no expert, just a shooter who loves the way my CZ pistols perform for me. Of course the action magic done on these by Mr. Angus and another gifted CZ smith have probably helped to spoil me a bit too.
Just my thoughts, and other members may have differing experiences. But for anyone who is concerned about some magic number of rounds meaning problems, given my personal experiences, I simply do not feel there is anything to worry about.
