I had a bunch of these 'errors' yesterday, not sure of the exact term, FTL maybe? Magazines are loaded with 10 rounds, magazine inserted and the top round severely angles up thus preventing proper loading when the slides released. Also had a bunch of FTL where the 10th round and final wouldn't cycle. no problems with 'ejecting' When the guns works it works.....it cyclews as fast as i can pull the trigger which is fast, very fast.
P22: Over 25K rounds but probably under 30K
Rounds: Mostly Mini-Mags and Stingers but a variety of other rounds as well
Slide: Broken somewhere around 20K rounds and replaced by Walther
Slide spring: Original
Magazines: 7 total. 5 'long slot' 2 'short slot'. Short slots have been 'retired'
Mods: full tuneup as per 'the bible'
So I decided to measure the 5 'long slot' mags, both lip width where the rounds are retained and spring length. I also made an attempt to measure spring strength.
1: .191" 4.09 .8lbs
2. .201" 4.00 .6lbs
3. .193" 4.10 .7lbs
4. .193" 4.10 .8lbs
5. .199" 3.95 .5"lbs
Mags 1, 3 and 4 are the tightest. Springs 1, 3 and 4 are longest and springs 1, 3 and 4 are strongest. Mags 1&5 are probably junk.
