CZ85Combat

Good for them they are standing behind their product.

Yes they are Springer Precision extension. I had a few of these and the set screw was a big PIA. I replaced them with CZC base pads.

It's all about the trigger. The fact is the safety model has a better trigger and can be improved more then the decocker models.

Stepped brass prevents bullet setback, = lower insurance cost. Lower internal case volume requires less powder to achieve the same pressure. in today's market less powder per round = cost savings. Even 0.03gn powder savings adds up when you are loading million of rounds

Blazer brass is Farley clean

I started shooting a dot on my Shadow in 2013 because I could no longer see sights, was forced into open. lobbied for production optics. What we got was CO for Tupperware. Now that the weight limit is gone we see growth of CO.

The AMG Commander is the one that I like the best.

What type of shooting do you plan to do?

I have the CZC plate system. I have not had any problems with the plate system and works well with good fit & finish.

N340 is not the powder you want for 9major. Did you check for over pressure signs? Trying to make 170Pf with N340 you have to be at the edge. Get some N350, 3N37,3N38 or Major pistol powder

It is a little on the fast burning side for major loads. Lots of caution should be taken!

You need to make a bulge buster. I use a Lee 9mm Makarov Carbide Full Length Sizing Die on any 9mm that fails case gauge.

All of the alternative powders will be just as hard to fine as 3N38. No one has any in stock, when it comes in it sells out very fast. You will have to watch Powder valley & Graf & Sons website and check every hour of everyday to snag some powder.

N340 is on the mid-slow end of the burn rate. For a good CO load you want to look at a faster burning powder. Like N320, Clean Shot. Sport Pistol.

I have loaded about 1000 rounds that I shot out of my CZ SO1 Shadow with N310: 125gn TC Blue bullet 3.4gn N310, @1.150 128PF

I think it was edited.

OP is @ 1.160" SAAMI max is 1.169". Op is looking for more velocity out of this round, experimenting with shorter loads may give him the results he looking for without adding powder, and with the price & availability of reloading components every little bit counts.

Your at the upper end of OAL, try 1.140"

In my CZ SP01 Shadow, I have used 3.5gn N310 with 125gn Blue Bullets @ 1.150" 1020fps, ES 27, SD 9. Mix brass & S&B primers

Your pistol shoot good groups in a ransom rest at the higher PF, but in your hand the recoil from that higher 149 PF load will result in larger groups and slower shot to shot times. The balancing act is to find a load that shoots the best group with your hand for the type of shooting you are going to be doing(Target vs bullseye vs USPSA). If you are shooting any of the action pistol games you don't need 1.5" groups. You will score higher with the 2"-2.5" group(129pf load) that lets you shoot faster splits with good enough accuracy for the game you are playing. Generally in pistols you will get better groups with lighter bullets as they are loaded to higher velocities.

One thing to keep in mind is that your Glock "carry gun" only has a small one or two port comp. Open guns have 4 -8 big ports or more. Your small comp will be over powdered long before you get to a 9 major load. Building a load that has more gas then your comp can use will only result in more recoil and broken parts. A test you can do with your gun is to shoot a USPSA target with the muzzle 2"-3" from the cardboard and see if the cardboard rips from the gas or is there just a bullet hole. If the cardboard rips your load is over powering the comp. An efficient comp and load combination will have 85%-90% of the gas being used in the port of the comp. Loading more powder to generate more gas then the comp can use efficiently will be wasted out the front of the comp. So you should be looking at a medium slow burning powder. Powders you should be looking at: N330, WSF, BE-86, N340. It's not velocity of the bullet you are looking for it's the gas produced to reduce the muzzle rise. Lets look at 1070fps - 1180fps with a 115gn bullet. A faster burning target powder will get you there with about 4.0gn - 4.5gn of powder, with the medium slow burning powder will get you there with about 4.8gn - 5.4gn of powder to get the same bullet FPS. The slower burning powders are using more powder to do the same work. you get the idea. The Slow burning powders that are typically used in an open gun will burn dirty at the lower charge weights that you would use, at the higher charge weights most of the gas will be going out the muzzle.

For the past 16 months I have used 5 lb of N310 in 9mm with 125gn blue bullets, shooting two times a week + some weekend matches. I have seen no temperature sensitivity.

I load N310 for my steel Challenge load. 115gn RN Blue Bullet, 3.4gn N310 @ 1.130 1009 fps very soft shooting. A 10# recoils spring is needed in my SP01 Shadow.

Is your recoil spring long enough? The P-10F takes a longer spring, P-10C spring might be short in the P-10F.

I use .356"
