  1. Having built a commander 1911, that reduced rearward travel and lighter slide makes them finicky (at more so than a 5" gun) feeders. If Dawson came up with it for a short open gun, I would suspect it was to improve feeding with light recoil springs. The extra travel means the slide can get more of a running start before it contacts the top round in the magazine. It also gives the magazine more time to push the column of rounds up into position.

    Interesting article about recoil springs and recoil timing: http://www.shootingtimes.com/gunsmithing/recoil-spring-rate-affects-timing/

    But what do I know, I just maul perfectly good 1911 parts for fun.

    I seem to recall those being the answers that Dawson gave for that back when he was selling the stroked shorty openguns.

  2. So far in my search for carry optic happiness I have shot an rmr, cmore sts, and an original delta point all are in the 3moa range (as those were the ones friends had who were willing to let me borrow them :-).

    The delta point is hands down my favorite (though I wish I had been able to borrow one of the 7ish moa triangle to try as I suspect I would prefer that as it would be similar to the dot I have settled on in the fullsized cmore on my open gun).

    The window on the rmr and cmore sts were too small for my tastes. Both of them seemed to have some optical distortion of some sort that the delta point doesn't.

    To me the delta point is about like looking through an eotech with a smaller lens very clear no distortion. The problem with the delta point is they seem to have discontinued the original and have just started shipping the new pro version which seems to be a good bit more expensive.

    I am anxious to put my hands one one of the new Sig Romeo rds but haven't found anyone local who has one (not sure they are shipping yet?) Also interested in the vortex (I think it is the venom) one of the local guys has one but I haven't had a chance to see it yet.

    Lots of these things seems to only come with a 3moa dot which I don't particularly care for. I shot a small dot in the cmore in my normal open gun for a fair number of years and I like the precision but moved to an 8 moa dot a few years back and that seems to be a much better choice with good accuracy but better speed.

  3. You do not want vise jaws wider than 4". Any wider and they start to get wider than the parts of the gun you're trying to hold on to.

    I'm a gunsmith and I live on my vise. We used to have a 6" vise at work and it drove me nuts. You don't likely need the vise to open as far as I do, so buy a 4" model if you can find it.

    When you mount it on your bench, try to set the height so the top of the jaw is at the same height as the tip of your elbow. It's much easier to file flat at that height.

    Look at the soft jaws from Brownells, part # 100-003-410. I built a set of aluminum jaws I really like from some aluminum angle iron I bought at the hardware store. For sight work on pistols, I line the aluminum jaws with business cards so I don't need to clean aluminum marks off the slide.

    +1 on the advice about the mounting height on the vise. I struggled trying to be able file things flat for a long time till one of my buddies who was a machinist clued me about the importance of that.

  4. If all you care about is grip size find a para ordnance p18 lda (limited or equivelent if you can find one) and send it to someone like jim anglin to get the trigger done. I think those are still legal in production. Can't imagine a gun with a chunkier grip...

    It's certainly not all I care about. It's just something I need with my size hand. Notice I said "competitive" handgun in the first post :) I'm looking for suggestions that I can look into and eventually pick the best option for.

    Oh don't get me wrong I never shot one all that well back in the day, but I think Todd Jarret managed to win at least one national with one. Course then again I think Ben won at least one national title with a Beretta so no proof either way there :-)

  5. Shot my second match in carry optics bit of an adjustment going from cmore on an open gun to delta point on the back of an m&p core. So far I am enjoying it. Gives those of us who have a problem seeing the front sight somewhere else to play.

  6. I just mounted one on a S&W M&P CORE 9mm and it works great. I did have to modify the slide and one of the mounting plates that came with the gun. Also needed longer screws. About 1000 rds through it and no problems so far. with the CORE cut on the slide it does mount lower.

    Could you describe or take a picture of the mods you had to do? I am going to shortyly find myself in the same boat.

  7. The Redding die is great for the micro adjustment. It does not have the "flip-flop" stem but it is still worth the extra money.

    I also use the Lee U die it's a big plush when using old brass.

    Hornady new dimension seating dies can be used with their micrometer stem, and come with both ogive and flat seating plugs. They also use a floating sleeve to align the bullet.

    Yep these are my preference for a seating die.

  8. Never unlocking the half nuts like can is suggesting is also a good idea if your lathe is less than great (cheap or worn). I find the threads seem to tun out nicer in that situation with that method. On my monarch it doesn't seem to matter that much so I do it like tool guy suggests.

  9. Umm. There are 55gr fmjs and then there are the hornady 55gr fmjs. I have found the hornadys bullets from the handy 6000 pack I use with my hand loads to shoot significantly better than normal m193 ammo particularly over h335 in a lake city or wcc case in most (but not all) barrels.

  10. lancer long length for 16" is really nice. nut is exactly the same as JP, if you happen to be going from those.

    can anyone else confirm this? will the Lancer hand guard work on a JP barrel nut?

    If I can remember I'll try it tonight as by chance I have one of both on my bench right now.

    thanks

    So at least the lancer that I have and the jp vtac nut that I compared it against are not the same. The outside of the jp part that screws onto the upper receiver is round where the round float tube slides on. The corresponding Lancer part is octagonal as you might have expected to match the octagonal float tube. Now there could be a different lancer tube?

  11. caspian guy there is a grid on the wall behind the gun, yes it could be bigger however in this situation doing the testing in an open indoor range, this is actually a pretty good setup and gives people a look at how the guns are recoiling in atlas's hands.

    I'm not sure if a ransom rest is a good idea do to how the guns are held. Maybe a sand bag to see how high the gun lifts up off of the bag , but there might still be too many variables.

    IMHO, just keep the guns in atlas's own hands, so that his personal grip pressure stays the same on all the testing, and then people can decide for themselves which combination of gun, load, recoil springs, etc. is shooting flatter. It's always good to try different combinations to see what is possible, and find out which feels best in your hands.

    Duh... I see the grid now... sorry about that.
