Had issues with not cycling.. this fixed it
Old spring was about 3 1/2 inches long.. this one was about 7 but 5 compressed.. thought it was wrong one, then pulled old one out to match it.. exact same... really had compressed.. my pistol was from 1930's.. so not normal.. but glad to have found a good replacement, can't wait to get to range.

Good survey of math applications.
Lots of practical exercises for each math technique shown.

Fast and reasonably priced
The memory allowed me to go to 16GB in my laptop, which when combined with a softdisk ramdisk program allowed me to speed my system up to where ev erything pops. Its awesome, can recommend it.
