BlkHawk73,
On second thought, forget what I said. Take just the handgun portion now. The refresher would do you good and you would learn some tricks since Mas's "Stressfire" is different from the "Modern Technique" taught at Gunsite and TR. You can take the legal portion later and you'll get the whole LFI experience in the end, just in smaller chunks. That helps with the financial hit as well, since you'll only have to pay about half as much each time.
RavenVT,
Just bring good quality factory ammo in a normal velocity range. It doesn't have to be your defensive ammo and I actually reccomend that you NOT shoot your defensive ammo for the majority of the class because of the expense.
What Mas doesn't want to see is downloaded "baby fart" handloads like those common in some of the action pistol games. You won't get the most out of the techniques if you shoot artificially reduced recoil loads.
I do reccomend that bring about 100 rounds of your prefered defensive load. At the end of the course you'll shoot a police style qualification exam and your score will be recorded and retained by both you and Mas. In addition to your score, the weapon make and model AND the ammo you used is recorded. I reccomend you shoot with cheap FMJ's that match your defensive ammo's bullet weight and POA (or are at least close) and then switch to the defensive ammo near the end of the last day. Try to time it so you shoot at least two or three strings BEFORE the qualifier so you can make sure the ammo runs OK in your dirty gun and then keep with it through the qualifier.
At the end, you'll have documentation of your training and with your prefered defensive pistol loaded with your prefered defensive ammo.
(If the ammo won't run with your gun dirty, switch back to load you were using or switch to a second gun that you know works with that ammo and handles the same as the gun you've been using. You don't want to mess up the qualifier)
When I took LFI 1 I brought two CZ-75's, one to shoot and one spare, 600 rounds of Winchester White Box 9mm 115 gm FMJ's, and 250 rounds of Federal 9BP 115 gr 9mm JHP's. I think I fired about 400 rounds of the white box and about 100 rounds of the Federal. I never needed the spare gun, but it was nice to have.
