I bought my CZ 100 .40 cal (2003 version) about a month ago at a local pawn shop. It was the least expensive gun in the case, a whopping 235 dollars. She has a lot of holster wear, so mush so, that I think she might be a CZ cop surplus gun. Upon field stripping she had a ton of dust, sand, pebbles in all the mechanisms.
I dismantled it to the limit of my abilities and cleaned the crap out of it. I then oiled it with a silicone spray (Liquid Wrench). Then took a few days to read the posts on here from 2002 to 2004 and still reading to make sure I don't miss any cool tidbits. So, after all that, I finally got out to the range and fired of a 100 rounds of FMJ flat nose. I found out that all drama about the trigger is a bunch of hype by closed minded, or inexperienced people. I own ten handguns and all triggers are different. As I shot my first 10 rounds at 7 yards, I had maybe 2 rounds pulled low due to the length of pull. But, after a few mags. I was putting 20 rounds in a group the size of my fist. This is from a 4 inch barrel, if you don't call that an accurate firearm, you're a moron. As my range-master used to say, "It's all about sight alignment and steady trigger pull." You can shoot anything with those 2 simple rules.
The best part of my range time was at the end. You never know how important those two little ports are in this 40 caliber handgun are until you fire off-handed. I always fire my last magazine left handed with no support. I think this may be my most accurate handgun off handed. It's light enough for my weak hand and the ports make recoil controllable after a 40 S&W goes downrange.
I will get her refinished add an IWB holster and make this my primary carry gun. It's only a half inch taller and one inch longer than my P-11. The weight is nearly the same.
I could not be happier with this gun.
