Copper Plated X-Treme bullets at 355 tumbled out of the Walther Q5 Match SF. RMR Match Winner FMJ at 355 run fine and are very accurate.

I tumbled about 300 9mm rounds after loading and it seems about 1 out of five the primer goes off and I get a squib. Yes they have powder in them. I've never tumbled after loading since. Just bad luck? or has this happened to anyone else.

I use 124gr RMR Match Winners with 3.9gr of American Select at 1.125 Oal. Avg 1074 fps for 133 PF, 30 ES. Very accurate, low smoke and clean.

If given a choice with target position when shooting strong hand or weak hand is it better to shoot targets out to in, such as right hand shoot right to left and left hand shoot targets left to right. Or does it really matter.

I put a case feeder on my 550 and never did get it to run great. I have a 650 with a case feeder that runs flawlessly. I took the case feeder off the 550 and use it for my Case Size Roller now. It works flawlessly too. Like I said I tinkered and tinkered and never got the case feeder to work right with the 550. It takes less time to just hand load the brass into the 550.

When you compare the Shadow 2 to the Walther SF PPQ or PDP remember the double action first trigger pull of the CZ . The Walthers have the same trigger pull each and every time. With the Walther Dynamic performance trigger the trigger pull is fantastic. I also shoot and have a CZ Tactical Sport. The 2 guns have the same grip angle and you can pick up either and acquire targets instantly.

looks good. Legal for Limited Optics and Open.

you can use a 13lb recoil spring but I had to tweek the firing pin safety spring and striker spring to get the slide to cycle reliably.

yes 15lb spring is good.

I use Red Hill Tactical for my Q5 SF. When Limited Optics option became an option I talked to a M class limited shooter and asked him what he would suggest for a holster. He said he had tried Carry Optics for a couple months and he found that the regular Red Hill Tactical gave him a better and more consistent draw than he got with his race holster.

I installed the Dynamic trigger in 2 of my Q5 SF. The trigger weight didn't seem to go down but I didn't measure it. Two years later they have lightened up quite a bit...still haven't measured them. I use the SF for USPSA.

I had a port put in the right side of my chest Sept 2022 and it's still in. I did some heavy chemo throughout the winter and shot some indoor matches. I've lost over 40 pounds from the time I started chemo 205 down to 165. Anyway I have had no problem at all with dry fire or matches with pistols. I have not and will not try PCC or rifle. I think my port could be damaged from recoil.

I found these for 10/22. Maybe I'll order one just to check it out. https://www.tacticalinc.com/catalog/category/774/614/2176/2531
