These days? Less than I'd like.
1 or 2 times per month. Two firearms, usually (those that are regularly carried): G19/32 and the 1911Sc commander. Practice inlcudes:
Strong side, 1 handed (50% -> 90%) ot the rounds fired;
Weak handed: at least 1 magazine;
Lots of slide lock with various numbers of rounds loaded;
Load some empty shells to practice clearing jams and FTFs (have the partner loaded in random order, random amounts);
Use abstract targets so it forces me to visualize (FBI "Q");
Number of rounds fired: ~200 -> ~ 400
Wear the exact same holsters I carry.
Distances: 70% at around 10 yards, max (usually 10 -> 15 feet);
Elapsed time: 1 hour, max.
What I don't do that I should: practice more with the the 442 (carried a lot in the warm months); it's just not fun to shoot!
