Sees Sights

Sees Sights (6/11)

  1. What extractors is he putting in? I have an SVI breech with spring extractor but I've had some issues with it. Im looking at going back to the good ole Aftec.
  2. CCI Minimags are definitely the most reliable but honestly, the 1911 conversions will have issues for all the reasons mentioned before. You can play with the springs to try and give the slide a little more energy ejecting. When I ran steel challenge, I tried conversions and other 22s but ultimately the old faithful Ruger 22/45 or other Mk variant was the best option. Those with decent mags and Minimags will run 100% if clean.
  3. Having lost a lot of soft tissue between 4 deployments as an Army Ranger, I will highly recommend PT type exercises for your knees and ankles. Specifically, exercises that strengthen the soft tissue so that it can hold up to the hard cuts you do in USPSA. Think wall squats with a ball, or squats with a band around the knees, resistance band ankle exercises, etc.
  4. They are expensive but the Salomans are great shoes - I used to do Speedcrosses but now use a combination of those and the Outlines: https://www.salomon.com/en-us/shop/product/outline.html#color=49396 These are great for everyday and match uses - they have plenty of traction but traditional laces and are very comfy.
  5. Hey partner - My CZ 1 barrel is the slowest of a bunch of guns I run minor through, while Glocks are the fastest. On that note, the Glock isn't as accurate with the really fast powders - I actually like N310 which is super fast, and Titegroup which is a little slower but still really fast.
  6. I see about a 15fps drop between my Gen 4 G34 and my Gen 5. That being said, with Blues and Molys, both guns are about 30 fps faster than non-Glock counterparts, i.e. CZ and Tanfo.
  7. I worked up a great feeling minor load for a Czechmate with 115 Blues and 6.8 3N38 - the gas really helps work the comp but its super soft and flat.
  8. CZ Custom has SP01 Shadow first gens that are cut for their plate system - I got one for just over $1000 and it was a great deal. The plates are easy to find and work very well. Of note, I prefer the ergos to the original CZ Shadows over Shadow 2.
  9. The SRO is a very good optic, other than the fact that 1 of 2 new ones I bought died after a few hundred rounds. I called and got a rep after 2m of waiting; the guy was super polite and I got an RMA. About 2 weeks after they got it, I got an email saying the sight will be covered under warranty. It has been a month since that time and nothing back, but they did say there is a big backlog for service. That to me is also an issue and indicator. Long story short, when they work, they work very well. For context, Ive had more SIGs die than Trijicons. The only optic that has never failed me is a Cmore Slideride - other than that, you name it, Ive seen it go down.
  10. When I went from Glocks to CZ for production, I had a few hiccups with stages where the first shot is steel or a tight paper engagement at 15 yards and further. I understood the techniques previously mentioned but didnt apply them in real life situations. I took an 8 inch round steel plate, and head shot USPSA at 20 yards and drilled double action ad naseum. It was part comfort and part confidence but after blowing through many rounds (ah the old days where primers were less than 3 cents per) no more issues. Lastly, try different techniques - dont take anything said on this forum as gospel - different tehcniques work better for different shooters.
  11. Fortunately the 2011 is great for changing out mag buttons - I would try the beefiest one you can find. Really the only issue is when you have a mag release so big, your support hand accidentally punches it during firing as the gun moves during shots.
  12. Hey partner, on my Instagram I have a few videos to help with the discussion thomas_koh_usar_cmp - breaking down partially, fully, etc, is a matter of efficiency. Since every transition is different, its hard to use a general rule. For R to L transitions with a pistol for a R handed shooter, if you have more than 1 step, not the USPSA make ready fake step people take, but both feet coming off the ground and touching again, it is generally good to break down and release. The fractions of a second that add up for situations you describe is building the grip back efficiently so your on the trigger as soon as possible in the new position. Look at your videos and see if the gun is up prior to the window of shot opportunity opening.
  13. Talons are really easy to throw on but not as cheap as some of the Home Depot posts; the carbide grit is really worth the trouble if you plan on shooting a lot of matches.
  14. This isn't what you're looking for but have you looked at the IFG Stock Master series? I bought a Stock Master for production and then bought a replacement slide from IFG and had it milled for CO.
  15. BlackBulletsInc has been super fast over the last few weeks - 125 and 147s.
