  1. ive had good luck with 4.3 grs of w231 and bayou 160 gr RN with a COL of 1.555. PF runs about 128 but is still a soft load out of my GP100. I also had no issues with ejecting spent cases during my reloads. when i get some time i am going to experiment with some real light loads (around 3.6 grs of w231) to see how those are build up wise.

  2. math aside, your best bet is to pick out a few good shooters who are "classified" above you and compare your match times to theirs. this will push you to get better and as you catch/pass them look for more shooters to compared your scores to.

  3. Would be shooting CDP. The lower part of the back strap safety the hump lol . My problem when shooting my hand was coming off the back strap and would not fire. We built it up with some welding to .. The gun fits me really well now. Hope this makes sense.

    My other question the 1911 had ambi but only could get single thumb safety.

    Thanks

    so you built up the beavertail/grip safety for better engagement in your hand? or did you change the mainspring housing from flat to arched?

    you can swap from single to ambi safety, just be careful of the weight as you make modifications

  4. I have small hands and was having problems with a good puchase. I replaced trigger for shorter one undercut underneath trigger guard. Slim grips I had to put a Gunsite thumb safety. I also had the backstrap built up. The last thing I did was extended slide release. Had stippling done to front of grip. Can I use this for IDPA?

    Pictures would help. Would you be shooting ESP or CDP? every thing sounds good for the most part. my concern is, what do you mean by "built up the back strap"? and what is the guns weight with an empty mag? 43 oz is the limit for ESP and 42 oz is the limit for CDP. Hope this helps.

    http://idpa.com/Documents/IDPARuleBook2005.pdf - pgs 21-24 gives you the list of "approved" modifications.

  5. way to go! i had a simular experience last year. I had been shooting SSP for two years and was a high MM. Classified in october for SSR with a brand new gun and borrowed holsters and speed loaders and squeaked into SSR SS.

    Happy shooting!

  6. ive found that speed loaders are no more expensive that production mags, im running safariland comp III's with my GP100 and using pouches from CPWSA. your brass does land in a nice neat little pile so policing your brass is easy. If you have a buddy that you always shoot with you could have them pick up your brass and loaders too if your that concerned about it.

  7. I used a P30L for IDPA for 2 years and went from novice to sharp shooter. You can be competitive with it, but it could greatly benefit from a trigger job.

  8. Is it throwing them all around or are they just high? A higher velocity bullet will hit lower because it is out of the barrel before it recoils up as far.

    the "slow" loads i shot were quite high, around 4 in high at 40 yards. this happened to me and another shooter in the same session.

  9. I am shooting a 4" GP100 chambered in .357 mag. I am set up to reload .38 spl but i noticed that my gun does not like "soft" .38 spl loads. I cant keep my light loads (3.6gr W231 & 160gr LRN ~750 fps) on paper at 10 yards to save my life, including Remington 158gr LRN factory ammo. When i shoot remington 125gr +p ammo my POA and POI is spot on. My reloads that had higher velocities (4.3 W231 & 160gr LRN @ ~800 fps) also shot well. I only had time to do some informal testing for these loads and shot them free style and not off a rest. I would like to shoot the lower velocity rounds as i can get back on target faster, but its not necessarily a deal breaker for me.

    Now my questions are:

    Do i get my forcing cones re-cut for .38 spl or do i keep the gun as is and load for higher velocity?

    Do i get a new cylinder chambered for .38 spl and swap in with the old one?

    I dont have a ton of money to throw at this, just looking for some input and who ya'll would recommend for the work should i go that route.

    Thanks

  10. my 4in gp100 likes 4.3 gr of w231 under a 160gr LRN bayou bullet at 1.555 COL, mind you the forcing cones are cut for magnum rounds. on the other hand my S&W 642 preformed well using 3.6gr of w231 using the same bullet and COL.

  11. i have shot a couple of matches with my kahrs P/K 9's. they are fun to shoot and you will get some funny looks (at least i did when i shot my K9 for fun) you would be in Stock Service Pistol (SSP) just be careful with what ever mag pouches you use. i was shooting a bug match and i had two rounds come out of the mag and stay in the holster...

  12. i would guess that its esp because your essentially "adding" a flared mag-well which is prohibited in SSP

    EXCLUDED Modifications (NON-Inclusive list):

    1. Externally visible modifications other than grips or sights.

    2. Robar style grip reduction.

    3. Add-on magazine well opening.

  13. if you have a FL steel guide rod and swap it with an FL aluminum one you will gain about .9 oz back. you could mill out the underside of your grips a bit too. what mags are you using? dawson 10rd mags with al base pad are about .3-.4 oz heavier than my metalform 10rd mags with plastic base pads.
