Shot this last night. It was 4 stages of USPSA. 2 were with flashlight, 2 were low-light (no flashlight allowed). I used my M40 carry with tritium and my M40A1 with skinny fiber optic front. It probably is not kosher to switch guns that way, but this was a fun match and I wanted to test things. There were 8 Production shooters in this Night Match. Stage 1: a single flare was the light, 4 small pepper poppers at about 20 yards, and 2 arrays of closer paper targets at the sides. I used my M40 with tritium. Tritium works, but I was focused on the front sight and did not line up the rears carefully for the long shots. Was no problem at typical close "real pistol fight distance" on the paper. The steel cost me way too much time, and I turned in a mediocre stage score. Lesson: front sight is not the only important thing. Place: 6/8 Stage 2. Flashlight stage. I shot this with the M40A1 and a fiber optic front. Used the flashlight in the "back of support hand against back of shooting hand position", and it worked well. I shot this stage quickly and accurately for a good score. Lesson: That flashlight position works well with standard sights. Other guys didn't think so. Place: 1/8 Stage 3: start from a chair, get up and flip on police light bar (flashing cop lights). Run to table pick up loaded gun and shoot 4 targets with no-shoots and hard cover, medium difficult shots. Mandatory reload, engage next array of 4 similar targets. I shot this one fine. Lesson: Tritium sights are an advantage in low light. Place: 2/8 Stage 4: Flashlight with fiber optic sight. I did OK, but after one reload I lost a second or 2 fumbling for my light. Then I forgot to shoot one partially hidden target on the last array. I shot this stage at blazing speed, and if I had not forgotten that target this would probably have been an easy 1st place, and a big help in score. Lesson: Mentally rehearse the stage, you moron. Stupid fricking moron.... Place: 5/8 Other lessons: 1) I was utterly UNimpressed with the vaunted "blinding muzzle flash at night". All guns were standard .45, .40 or 9mm autos. And the flash was of no consequence whatsoever. There were no Open guns (the kind with comps) in my squad. 2) Tritium helped in the low light, A front tritium with plain rear would likely be adequate for "real guns". The rear dots were useful for the longer shots. 3) Malfunctions in the dark stink. I did not have any, but others did. My Steyrs were flawless, of course. I didn't see my final score, headed home. It was nothing special I'm sure. I shot .40 minor PF ammo in Production class. Used a 2 Alpha belt from CED, a GF Oak kydex holster, and my quad mag pouch from Rich at Custom Carry. Also used a CED tactical light.
