    Switch divisions if laws change?

    (flame suit is on so...) IMHO the greatest challenges to shooting skills lies in Revolver, SSTK, Production, Limited, then Open Divisions in that order. Why, because accuracy becomes a greater requirement as Mikes can force extra unplanned and possibly flat footed reloads - real time killers and USPSA scores are more sensitive to time than accuracy (to a point). I like SSTK because I like the challenge however I often shoot Limited because I don't like to shoot alone. I'd enjoy seeing more SSTK shooters but not because of legal issues. But, I doubt a retro active bad would or even could happen.
  2. Another vote for 130-135 PF. Gun is reliable, steel hits are stronger and more effective, and no worries at chrono. If you really want low recoil got to 147 gr or even 160-165 gr bullets at 130-135PF. A 140-145PF will start feeling harsh but 130+/- will bee just fine.

    Anyone loading165 grain 9mm?

    I've used them and like them. More spendy then 147's ore 124's but very nice to shoot. I've used N350 and in general I like to use slower powders to avoid pressure spikes. I'm not good enough to detect any big recoil difference between most powders so I opt for lower pressure. 3.7 gr of N350 gave me ~130PF out of a custom 9mm 1911 and an M&P Pro 9.

    Best scope for 3gn

    I have a Razor HD and a Strike Eagle. There is a difference between the two but I feel the Strike Eagle is a hard value to beat. If you want to win, I'd say get the Strike Eagle, three cases of ammo, Strelok Pro, and learn how to get first round hits out to 400 - 600 yards.

    Question about SO test oval/keyhole bullet holes.

    Typical. One question with 25 responses out of which maybe 3 or 4 try to help the OP understand and tell the difference between a low angle oval hit and a tumbling bullet hit. the rest ragging on IDPA SO and/or IDPA rules is some from or another. To the OP, low angle hits are very much an oval shape and if you can tell its greater that 2 bullet dia its a no-hit if you can't the shooter gets credit. If the shooter disputes your call call the RM or MD and let them sort it out. Tumbling bullet hits produce a long but ragged hole distinctly differnt. However if you know the angle the target was engaged at that will help you determine if could or could not be a low angle non-scoring hit.

    Black Nitride vs Titanium aluminum Nitride PVD

    Nitride chemically changes the surface of the steel and case harden's it. The "black" will burnsih on corners, high spots, and rubbing surfaces but the protection is stll there. Everthing else is a coating that can wear or even chip (to greater or lesser extents) in some cases exposing unprotected metal.

    Question about SO test oval/keyhole bullet holes.

    Haven seen a number of holes from tumbling bullets and high angle hits its very clear which is which for the vast majorty of time (very ragged holes vs smooth ovals). Add in the context of the traget and presentation mode (drop turner vs face-on) it's really hard to confuse the two. The only potetnally confusing situation is a good hit with a tumbling bullet on a drop turner. If you can't honestly tell its oval then the shooter gets the benifit of the doubt. FWIW in setting up or even just breifing a stage you should see where high angle hits (if any) are possible. You should be able to watch for said questionable hits, warn shooters, or adjust the stage to prevent them.

    Black Nitride on 2011?

    The black surface is not the protective layer. It is a side effect of the case hardening process. You can polish off the black and you will still have the protective layer of carbonized steel. You will see this wear on high spots / corners as well as flats that rub together. The "polished" surfaces are even smoother and slicker, just not as attractive looking. I do not recommend the treatment of very small or thin parts that see a lot of impact stress. I've have had a couple 1911 link's fail after treament and the spur of a FGW lightweight hammer shear off. The process went so deep it made the parts brittle. Ntride process changes the surface of the materal, hard chrome is a layer of material.

    How accurate can a 1911 be? Or any handgun really.

    Consider the 50 yard Bullseye tgt with its X-ring at 1.7" dia and the 10-ring at 3.4" dia. Top shooters can score in the high 90's with more than few X's shooting strong hand only. I'd say those guns have a mechinical accuracy of ~1" at 50 yards, maybe less. I the NRA record is 2680 (out of 2700, i.e. 270 shots) with 159X. Jerry M. has hit a 18"x24" (think) steel plate at ~1000yards with a 9mm revolver using a red dot sight as I recall. The shooter is only limited by the gun and gun can do no better than the shooter.

    9 Major vs 38 thread # 2,927,642

    A major aspect of the game is mental and having confidance in your equipment and ammo helps in that regard. If you "think" one lets you shoot better than the other that's the one you need to go with.

    Recommendation for factory .40 ammo

    I've chrono'd 40 cal Federal 180gr load at 171PF, Remington UMC 180gr at 179PF, and WWB 180gr at 185PF. I've not chrono'd Speer or PMC Bronze both feel between Fed and UMC. Recomend the Fed 180 gr TC load.

    "40 Open doesn't make enough gasto work a comp" ...

    Its more about gas pressure and velocity than just volume for the comps.
