I had a trigger job done to lighten it to about 4.5lbs pull in single action. It is MUCH better now. The heavy single action trigger used to make target shooting tough. Just dry-firing it, I noticed the whole gun move due to sudden "give" of the trigger. No more with the lighter trigger. The job cost me just $60 at Tugwell Custom in Santa Ana, CA.
Aside from that, another criticism is with the barrel. It will feed ball ammo just fine (100% reliable so far). Some bullets that don't "taper in" immediately from the top of the cartridge case will get into the rifling in the chamber, and cause some resistance to chambering. Once chambered, to remove the ammo without firing it can be a chore, since the bullet is already in the rifling and thus sticks in the chamber! Thus my feeling is that feed reliability "may be" compromised with certain types of ammo, even though I have yet to experience any jams.
Again, this isn't a problem with ball ammo, or any ammo that tapers immediately from the top of the cartridge case.
I'm going to see if my gunsmith can fix this by removing some of the rifling from where the bullet would normally sit (maybe an exta 1/16"). I wonder if the SW99 suffers from the same problem... probably not, since S&W has a lot more experience with different bullet designs.
One last gripe is with "cocking." Very awkward to get it "cocked" into single action mode once you depress the decocker. It requires you to pull the slide back about 3/8" and release it. Its too easy to pull back too far and end up ejecting the chambered round, or partially ejecting it, leading to a jam. It takes a bit of practice to learn to get it right each time.
Now for all of my positive opinions:
1. Best looking polymer frame gun available (or for that matter, almost any gun).
2. Best grip design for a pistol.
3. Its semi-compact (smaller than most full-size 9mm pistols).
4. 16 round "pre-ban" factory 9mm magazine still available from KY Imports. This is more than most "full size" 9mm's will hold! They also have 13 round .40S&W P99 magazines! $100 a pop.
5. Easiest gun to field-strip I've ever used.
6. Unique and useful cocking indicator, and loaded chamber indicator.
007. 007 will continue to use the P99 as his standard sidearm in the new movie "The World is Not Enough."
