Come on Bret, it's on the second page of the rule book: "Your percentage is based on your scores as they relate to the high score on file for a particular course of fire. To receive an initial classification, a member needs to have at least four unduplicated scores in the USPSA classification database prior to the monthly reclassification procedure. If there are more than four scores on file, the best four scores of the most recent six scores will be used. Scores are sorted according to the match date to determine which scores are the most recent. For matches that are Level I Specials, the scores are further sorted by the score percent in descending order. In doing so, the lowest scores from a special will be the first scores to drop out of the most recent scores on file. After a member has earned a classification, the classification system will look at the best six unduplicated scores of the most recent eight to evaluate the member’s current classification percentage. No scores that calculate to less than 2 percent are used. Also, to prevent unusually low scores from affecting your classification percentage, scores that are more than 5 percent below your classification bracket (e.g. a score of 34.99% for a C-class competitor) are not used for classification purposes. To guard against the possibility of incorrect stage setup or typographical error, scores that are more than 15 percent above your current classification bracket are evaluated at the time of entry to see if such a score would adversely affect your classification. In general, those scores are entered, but occasionally a score is so out of the ordinary it is not used and flagged with an A. So members can keep track of their scores, all scores received are entered into the database, but may be given a “flag” to indicate its status. The possible flags are: A —A score that is more than 15% above the member’s current classification bracket. B — A score that is more than 5% below the member’s current classification bracket. C — A score that is more than one class below the highest class in any division attained by the member. e.g. A member has a Master class in Open division and a B class score in Limited is submitted. This score will be flagged with C and not used. D — Duplicate course - a higher score for this course already exists in the most recent six or eight scores. E — A score that is not in the most recent six or eight scores. F — A score that is one of the two lowest scores in the most recent six or eight scores. Y — A score that has been used as part of the classification percentage calculation."

Unfortunately I didn't experiment with it very much as I am an Open shooter at heart, but I remember it feeling a little 'flippy', if I were to get serious about the idea I would take a bunch of weight from the rear of the slide and increase the stroke. The factory TS stroke is longer than the stroke of the 75B.

I shoot 9 major out of a TS in Open The first USPSA gun I bought was a TS in .40 for Limited, then in short order I converted it to 9mm, added a dot/comp and started shooting it in Open. I see your point that a Limited gun chambered in 9mm, cannot shoot Limited Major, I'm just not a big fan of Limited; it's like Open, but not as fun!

Two things: 1. You didn't read 10.5.9 correctly, it states "a gun without a decocking lever". A 2011 is a gun without a decocking lever, so it actually does fit into the exception so you would have to argue the shooter's finger was in the trigger guard for some other reason than to comply "with the 'Make Ready' command". 2. What is the motivation for the DQ? Is the practice of inserting a loaded mag for weight prior to taking a sight picture creating an unsafe condition? What are you trying to accomplish as the RO?

I've never owned a new one I've owned more than a dozen Tanfos and never has to deal with EAA on a warranty issue.

Like Mark said, if there's not a scoring advantage like in USPSA Limited, 9mm is a better round: cheaper, more capacity, and more flexible.

Given what you've described I suggest a 9mm TS, hands down.

Vihtavuori lists a max load for 3N38 under a 115gr JHP which makes 170.5pf: 9.4gr under a 115gr JHP @1.161" (listed under 9x21, but can be loaded in 9x19).

Try not to shoot "fast", take as much time as you need to break each shot clean, pay attention to where the targets are, where you will shoot them from, be safe, be helpful, and have fun!

My titanium comp'ed bull barrel 2011 with a plastic grip weighs ~42oz; a steel grip is about 7oz more and 2oz for a steel comp. I've owned a Ti comp'ed super shorty which weighed ~39oz all the way up to an all steel CZ Tactical Sport based gun which weighed ~54oz. Heavy guns might shoot a little softer, but I'm faster with a lighter gun. I like them in the low forties with light muzzles. EDIT: it occurs to me you might not be talking about Open guns, I like non compensated guns about the same weight, with a little more towards the muzzle.

Another great video of EG shooting on the move:

I didn't like the break on my TS with a 13# hammer spring, like you said: mush. If you do a good job polishing the SA trigger doesn't get much lighter with a light hammer spring and you just invite light strike issues. I have a whole box of factory hammer springs taken from DA/SA guns which I use in my SA guns; best I can tell they're in the 17-18# range.

The factory hammer spring is somewhere in the 17-18 pound range. Is lighter better? Boy that is the question isn't it? There are a lot of factors which effect the way a pistol feels in recoil: hammer spring weight, recoil spring weight, slide weight, frame weight, bullet weight, powder burn rate, firing pin stop radius, stroke length, the frictional coefficients of all the moving parts, and whatever else I'm not thinking of When it comes to muzzle rise, there is the initial lift when the bullet leaves the barrel, then the impact of the slide hitting the frame; the more resistance to the slide coming back, the more of the lift will happen in the first part, less resistance, more slide velocity. A square firing pin stop gives the slide the least leverage to cock the hammer, holding the slide closed longer while energy dissipates, conversely a firing pin stop rounded off like this one pushes on the hammer further from the fulcrum, giving the slide more leverage to compress the hammer spring. http://i1198.photobucket.com/albums/aa457/jjdurso/Mobile Uploads/IMG_20160227_065922_zps0r2rxpf6.jpg Personally I feel like a rounded firing pin stop combined with a heavier hammer spring can slow down the slide a little over a lighter hammer spring with a more square block. Long story short, I say leave the stock spring and smooth the radius of your firing pin stop.

Ah IPSC if you're in a place where you can get SP2 it is also very nice

Have you tried 115s?

3N38 or N105 will serve you well under a 115gr, ~10+gr

3gr of something fast under 100gr pills

I forgot to mention Chapo: if flatter is what you're looking for, you should try 115's, the comp works by using combustion gasses to force the muzzle downward, so the more powder, the more gas. When talking about Open guns there are two components to the recoil impulse: the vertical movement (flip, muzzle rise, etc.), and the horizontal (straight back recoil, slap in the hand, etc.), powder, gun, comp and PF being equal lighter bullets generally shoot flatter, but recoil harder in the hand, with a light gun like a Glock that may prove to be unpleasant.

Autocomp is on the fast side of Open powders, while loading for a compensated pistol it's important to have a good understanding of the effects of changing variables like OAL, powder, bullet type, ports in the barrel, barrel length, etc. As a rule of thumb, the faster the powder, the heavier the bullet, the shorter the OAL, the harder the bullet, the higher the initial chamber pressure, the looser the chamber, the more likely it is to have a case failure. It might be counter intuitive, but loading 9gr of 3n38 is (*in my observation) safer than loading 7gr of Autocomp. Ah the elusive flat shooting Open gun I'll start by stating, a 'flat' shooting gun is not a requisite to becoming a GM, in fact, most GMs I've seen shoot gun which don't shoot as flat as mine do, but they are GMs and I'm a B class shooter because they spend time practicing while I spend time playing with loads, comps and guns; we do what we do because we enjoy it and everyone has their own priorities. People like to brag about how "flat" their gun shoots and how "the dot never leaves the glass", but through my extensive use of slow motion footage I'm convinced that is largely imaginary I have a very strong grip, I've shot a lot of pistols with the best powders available and I have never shot a gun where the dot never leaves the glass. I have shot pistols where I didn't perceive an empty glass, but with the aid of the camera I can see the muzzle lift at which the dot leaves the glass is a small fraction of the lift exhibited by my flattest gun. Here's a link to my thread:

Which bullet are you loading and how long? 115s shoot flatter than 124s

I think Bevin does it, if not you can send it me

Slide mounted optics are legal in Carry Optics, frame mounted optics are not, you'll notice Mose Open shooters use frame mounted optics for the reasons you're thinking of.

You don't need to do extensive brass prep to shoot 9 major reliably. I use mixed range brass, dry tumble for 45 min and load, after loading I tumble again, chamber check each round in the barrel and place it in a plastic ammo box. I then run my finger over the head stamps and pull out the stepped brass (FM, INT and Ammoland) for use in practice. Since I adopted these steps my guns have run flawlessly. Here's the skinny on stepped brass: forums.brianenos.com/index.php?/topic/216083-first-case-failure-9-major/ For primers some use small rifle primers for 9 major, but I use small pistol, usually CCI or Winchester.

9mm mags are more reliable than 40 when shooting 9mm, I found the last round would jam every time.
