It's about time. Now maybe some SCSA shooters will take the course and stop using made up commands.

^^^^^^ This. I have several steel e2 grips. I don't see anywhere you could reduce the weight by any appreciable amount.

Maxim Defense roller delayed buffer. It will get you very close to JP-5 level recoil with typical loads. Very little recoil with light steel challenge loads. I use it in a 5 lb. PCC with 100 and 132 PF loads.

No. I said a frame mounted Slide Ride, as per the used Open gun the OP is considering purchasing. A Slideride is a red dot.

Some 2011 Open guns cannot be set up for minor and run 100%. I have one that will not, and one that will. The one that will uses a 6V recoil spring, a 17 lb. mainspring and a large radius on the firing pin stop. I use 124gr at 132 PF for minor. Any lower than that and it becomes unreliable. Muzzle rise is more than when I shoot 9mm major loads through it (with a 9 lb. recoil spring). The 38 Super barrel on the gun you list is worthless. You are never going to shoot it. A frame mounted slide ride puts the dot 2" above the bore. You definitely have to adjust for close shots. Since you only want to shoot minor 9mm, why not but a good, used 2011 Limited gun. The are quite attractive right now. Put s slide mounted dot on it and you are good to go.

If you are really dying to shoot SS, that may be the optimal choice. You get 10 round mags but have to shoot minor. Moving to 40 may not get you what you want. For example, Winchester White box 165gr only made 164 PF in my Limited gun. Same as you are shooting, except double stack. Everything else (at the time) was a lot hotter. Even if you reload, your options are limited. 45 brass is becoming harder and harder to find for free. Same thing with 40sw. So, you'll be doing the brass chicken dance after every match to recover your brass. You can buy once fired, but it will cost you 3 to 5 cents each for 40 and more for 45. Basically, if you shoot 45 or 40, you have to reload. It may not be worth the trouble for you.

What is wrong is the system based on percentages. Using the RFPI example above, decreasing the peak time does the following. a 2023 95% GM shooter must increase his total match speed by 1.05 seconds to get back to 95%. A 2023 60% C class shooter must improve by 2.5 seconds to get back to 60%. Generally, a more difficult task. In prior years when peak adjustments were larger, you dug the C shooter an even deeper hole. I understand the argument that a 1.05 second improvement may be more difficult for a GM than 2.5 seconds for a C. I just don't buy it. As I mentioned earlier in this thread, I finished my first season with .5 seconds to go to make A. The adjustment the following year added 5 seconds for A. So, I started 5.5 seconds down. Something similar happened again the following year. It can be frustrating. I don't know how you fix this while using percentage divisions. As it stands, the system makes it harder and harder for a B, C, D shooter to move up a class.

My bad. I said second video, because that was the second one I watched. It was actually the MythBusters video. In the MythBusters video, the slide started to move before the bullet exited in the :10-11 frame. It has not moved in the :38-39 frame when the bullet was out of the barrel. The slide moves at the start of :40. Neither is an optical illusion, so what gives?

Go back and look again. The bullet is out at the end of 38 and the beginning of 39.

In the Mythbusters video, the slide has started to move even before the bullet becomes visible. In the Vickers video, it has not moved until the bullet is completely out of the barrel. So, both sides of the argument are correct sometimes. I wonder what counts for the difference, other than recoil spring weight.

Nonsense. At the very beginning of the 38 second mark you can just see the nose of the bullet peeking out the front of the muzzle. The slide has not moved. Moving slightly ahead in the 38 second frame shows the bullet half out of the barrel. The slide still has not moved. Click ahead again and the bullet is at the end of the muzzle. Click again and the bullet is out and you can see the bright flame front. The slide still has not moved. Two more clicks and the bullet is out by an inch. Still no slide movement. You are correct in the slide has just started to move at 40, but the bullet is long gone. All of this is easier to see if you go full screen with the video.

Thanks Grumpy.

Yup.

I certainly wasn't. I thought they had done away with that.

Absolutely. My first year of SCSA I shot RFPO and OPN. The only two suitable guns I had. I got within 0.5 seconds of A in RFPO by the end of the season. Then the lowered peak by 5 full seconds. Frustrating. In my second season I got back to within 1.38 seconds of A. They lowered it another 5 seconds (might have been 4.5). Again, frustrating. I tried again the third year and got close. Every time I was edging up, I got dropped back because my older better times expired. So, I'll probably never make A, because I only shoot RFPO once or twice a year. I mostly shoot RFRO and PCCO now (and always in the Winter).

You lighten a slide to reduce reciprocating mass. As you lighten, you increase the weight of the recoil spring. So, the increase in slide velocity is not as great as you depict. Nor is the slide movement. A heavier spring increases the preload.

Lubing the buffer partially defeats the purpose. You want to retard rearward movement as long as possible.

No, it doesn't. You are classified after your first four stages. It may take you months to attend a match where OL and SO are offered. Many clubs do not have bays long and wide enough to accommodate.

This is child's play. Take it to a local gunsmith. He can do it for you while you wait 10 minutes.

If you are having 9mm accuracy problems, slug your barrel. 9mm barrels vary from very slightly under .355 all the way up to .359.

No. There have been many threads on how to tune your gun for a specific load. You want the slide to have enough dwell time at the rear of the stroke to pick up the next round. You want the sights to return to zero at the end of the stroke. If the sights are high, you need a heavier recoil spring. If low, lighter. You fine tune by varying recoil and mainspring weights and the radius on the firing pin stop.

FWIW, for exactly the same PF, 147 have slightly less actual recoil. In order of least to most actual recoil: 147, 135, 125, 115, 100, 95. How the recoil feels is different. For the same PF, 147s are slower going down the bore, so the muzzle has a tad more time to rise. 115s are quicker, so the muzzle rises less, and sights return more quickly. You pay for that with a sharper feel to the recoil. If nor for a spectacular deal on 6000 plated 124s, I'd be using 115s.

FWIW, I'm not a fan of extended base pads for extra capacity. I do have the CZC pads on my TS mags. Problems at first, but they all run now as long as the guts stay with the mag. No mixing and matching. If I still shot the gun, I'd buy MBX. I run MBX in 9mm and 40sw. Zero issues. Drop them, fine. In six years I've never had to tune a feed lip. I just changed springs in my 9mm mags after three full seasons of shooting. If you have the money to spare, go MBX. If money is tight, buy two and download your CZ mags. Use them for classifiers, etc. Or, in the odd event your stage plan calls for three mags.

You'll find your SDs are better with processed brass.

Possibly. Depends on the sizing die. With roll sized brass my Hornady sizing die does additional sizing. For 9 major I buy fully processed, roll sized, swaged, cleaned and polished once fired, same head stamp brass. For range pickup brass I use for minor, I give them to a buddy. He decaps, swages and roll sizes them for me. Everything sails through the press.
