Red dots can really accentuate how wobbly/unsteady your aim appears to be. Perhaps it means you're trying to chase the perfect position of the dot in the centre of the target and jerking the trigger as a result.
That’s very plausible, I was a bit distracted by the dot moving on the target. I assume the solution is practice?

I had my CZ shadow slide milled to accept a Holosun 507c. At 25 yards offhand I can hold a softball sized 10 shot group with the irons. With the optic it opens up to a large dinner plate sized group at 25 yards with the same ammo. I checked the optic, it appears to be mounted snugly to the plate and slide. With the optic I keep both eyes open, but I have to close an eye with irons, my right eye is very dominant. Unless the optic is defective, I am at a loss to explain how I am more accurate with irons. This is absolutely not the case with long guns, with them I am more accurate with the optic (red dot or scope) than with iron sights. Thanks.

I want to use my SP-01 shadow in carry optics. Obviously the slide needs milled, any gunsmith suggestions?
I am new to optics on handguns but I have a Holosun 512c on my PCC and like the circle dot reticle. I have done some research and it seems that direct milling to the slide offers advantages over using a plate. This leads me to the Holoson 507k as it can be directly milled to the narrow SP-01 slide unlike the 507c or SRO which require a plate. Is it a bad idea to run the smaller 507k vs larger SRO + plate for competition?
Also if I run the 507k some gunsmiths (Cajun) allow you to keep the factory rear site, will this help someone new to pistol optics find the dot or will it be something in the long run that just clutters up the sight picture?
Another reason I am leaning toward the 507k is it will fit on my P-01 and rami concealed carry pistols. I like to keep my competition guns as close to my carry guns as possible. I am a causal competitor, I do USPSA for fun, but I don’t want my equipment to handicap me either. Thanks.

I got a BCM SPR build in 556 & a Compass Lake .22 LR upper built like the BCM. I bought the CL 22 upper as a cheap way to practice on my SPR lower without spending a fortune on ammo, but I am questioning the merits of my decision. I mostly shoot at simulated distance targets at 25 yards designed to simulate targets at 50, 100, and 200 yds. But obviously the recoil and possibly the wind drift and drop are very different. Would I be better off selling the 22LR upper and just buying more 556 to practice with? Thanks.

Here are my opinions and my experiences, you don’t state what type of matches you’re shooting im going to assume uspsa.
Your assumption is correct. Sorry I forgot to mention in original post.

I have been thinking about jumping into the PCC division and have a few questions. I have pretty much settled on the JP GMR-15, however I am not sure which optic or magazines to get.
Currently I am leaning towards a Aimpoint Comp M5 for the optic because I want something that is not made in a developing country (China, Philippines) as I don’t trust the quality control of optics made in those countries. I also want an optic that takes a readily available battery (AAA for the comp m5). Is the Comp M5 competitive in PCC?
For magazines I was thinking of running a 33 round Glock mag with the Taylor Freelance +20 extension as my starter magazine with 3 additional Glock 33 rounders on the belt for stages with mandatory reloads. This would give me back up “big mags” in case the mag with the +20 extension failed. I will use the DAA Glock extended mag-pouch spacer in my DAA racer mag pouches. Would this mag set-up be competitive? Thanks.

I would get the CZC TS magwell that fits the IPSC box. I got the large TS magwell and had to remove a lot of material from it & the CZC basepads to get the mags to lock in and drop freely. I ended up having to bead blast my basepads because they were so ugly after I was done. CZC really needs to watch the tolerances on some of their parts.

Just picked up one of these scopes and need a mount for my 556 AR-15. Here are my priorities from most important to least important:
1 retain/hold zero
2 quick detach
3 won't DEFORM the rail when used properly, I understand it may leave some cosmetic marks,
3 allows the use of a folding back up iron sight
4 robust, bombproof construction
5 allows proper eye relief
6 ease of installation, will allow use of wheeler torque wrench
7 will return to zero after being removed
8 price
9 weight
Right now I am leaning towards this:

I like the large CZC magwell but it was a pain in the butt to get it working correctly with the CZC 140mm extensions.
I had to remove a lot of material from the inside of the magwell and then still ended up removing material from the extensions.
Ditto, if I had to do over I would have just gotten the CZUB or CZC IPSC magwell.
-
For pouches I run DAA racer mag pouches (plastic), buy them from CED and they will include a free modified spacer for the TS. I tried CR speed, DAA universal, and ghost 360, but the DAA with the modified spacer worked the best.
For holster I run a blade tech pouch on a ben stoeger boss hanger.

OP have you tried any of this? What are your results?
I have not tried anything, I was always gripping the gun hard, just not to the point that I induced tremors. Per the Leatham vid and my own facilties of discernment I decided to just continue gripping the gun the way I always had.
-
Is the factory trigger plastic or metal?
-
Thinner grips also help with reaching the safety.
-
How hard can you grip the gun without shaking?
I know it isn't just as simple as exercising the lean muscles for some people, but if you believe this can be overcome by strength workouts, I would begin there.
Hard, my deadlift work set is 455lbs for 7 reps. I have a strong grip, but when I death grip the gun I get tremors, I would bet most people have tremors when the squeeze at 100%.
-
I am reading Ben Stoeger's Practical Pistol: Fundamental Techniques and Competition Skills book. Ben recommends gripping the gun hard, but if I grip the gun as hard as I can, my hands start to tremor causing the front sight to move around. Is it really advisable to grip the gun so hard your hands start to tremor causing the front sight to move around?
-
Stu that older magwell is gone.
The TS takes the regular grips if not running a magwell. If running a magwell you have to cut them down to fit.
How did you cut the vz grips down?

You really wanna run the lightest recoil spring you can and the gun still operate with in reason. I run a 11# recoil in my shadows but need to try lighter. I also run a 11 in my tac sports at major and minor PF. the gun will track flatter with less heavy push into the hand translating into muzzle rise.
3. What weight recoil spring should I use with a particular load?
This is a very common but hard question to answer in exact terms and in most cases an exact answer is not possible. There are many factors which influence the correct weight recoil spring to use. These factors include the particular ammunition brand and load, individual pistol characteristics, individual shooting styles and your individual, subjective feeling of how the gun shoots and should feel.
The factory spring weight is designed to operate the pistol with what would be considered average loads, plus or minus a little. It is not uncommon for manufacturers to specify what they consider a factory ammunition load.
In general terms, the heaviest recoil spring that will allow the pistol to function reliably is the best choice - tempered by the above factors. As a rule of thumb, if your spent casings are first hitting the ground in the 3 to 6 foot range, then the recoil spring is approximately correct. If you are ejecting beyond the 6-8 foot range, then a heavier recoil spring is generally required. If your casings are ejecting less than 3 feet, a lighter recoil spring may be needed to assure reliable functioning.
Taking these factors into consideration, it then comes down to how the gun feels and performs when shooting - in your judgment. However, using too light a recoil spring can result in damage to the pistol and possible injury to you.

Recoil Spring Selection
A common problem with any auto loader is recoil spring selection. Many take the advice given on the net', which is typically incorrect.
Recoil springs will not lessen recoil by themselves, Newton's Law applies here: for every action there is an equal and opposite reaction. So the energy from recoil has to be dissipated.
Recoil spring selection for the average shooter is based on the ejection distance of a fired case. 6-8 feet is ideal. This generates the optimum slide velocity for reliable functioning and will let your slide stop live a long time.
Each pound change in recoil spring weight affects the ejection distance 1.5 - 2.0 feet.
Example: ejection distance is 4' with the stock 14# RS; to add 4 extra feet go to a 12# RS.

In all my semi auto handguns I run the heaviest recoil spring I can with the ammo I use and still get 100% reliablity.
For my SP-01 this means a 14lb recoil spring with a 13lb hammer with a 115gr load at 135 PF. For factory CZ mag springs I could see this causing malfunctions, but no problems for me with 10% mag springs or mecgar mag springs. CZ OEM mag springs are notoriously weak.
For my 40 TS this means a 16lb recoil spring with the factory hammer spring (20lbs ?) with a 165gr load at 175PF.
I probably have close to 40000 rounds or more in my CZ's and have yet to break a slide stop.
I tried the 11lb spring and couldnt tell a dimes worth of difference in the recoil impulse. Controlling recoil for me is more about my grip technique than anything else.

Cz ts trigger
in CZ
I don't think the 75 SA trigger will work in the TS. They have different trigger return springs. The custom shop flat trigger has been adapted for both the TS trigger return spring and the regular 75 trigger return spring.
-
It isn't a matter of if they are a factory. They applied for and received approval onto the approved factory gun list.
And you don't "need" a high dollar gun to compete or even be competitive. Want is a whole nuther matter altogether.
And, for the record--I think all of this is silly and the rules should be revised to reflect the original intent and eliminate some of this parts changing nonsense.
I wish it was more like single stack, get rid of the list of "approved" handguns and just lay down a list of rules of what is / isnt allowed. Single stack caters to 1911's, production caters to striker fired, DA/SA, and DA handguns.

Is an after-market slide allowed? I don't think so.
The 75 SP-01 Shadow is the model of firearm. The 75 SP-01 Accu-Shadow is another model of firearm.
Therefore, you can't change the slide of one model of shadow to another model of shadow. I might even see the bushing being called out as not the same contour.
21.3
After-market slides and barrels – provided they are the same length, con- tour and caliber as original factory standard.
SLIDES: Current rules remain in effect – You may replace the slide with an OFM or aftermarket slide which is of the same length, contour and caliber as the original slide for that model of gun.
If CZC and CZ-USA would stop changing model names every time they change a feature or even rear sight..
Why could I not put a CZ 75 shadow slide on a CZ Sp-01 shadow frame? The only difference is the markings (which an allowable aftermarket slide would have different markings), the length, contour, and caliber are the same.
Yes an aftermarket slide is allowed per 21.3.
-
So I'm really confused at this point.
Someone please correct me if I'm wrong, but here is how I understand it up to this point:
If you send in an SP01 Shadow complete upper assembly to be retrofit for an Accu bushing, the gun is illegal in Production.
If you replace the Shadow entire upper assembly with an Accu Shadow entire upper assembly that came directly from CZ, then it's legal. Per 21.3?
???
It's all legal until an RO moves you to open and it sticks.

Isn't the accu shadow slide the same length, contour, and caliber as the shadow slide and therefore be legal?
It's definitely close. you might be able to argue a slight contour change at the bushing.
I guess that depends on how they are defining contour.
How am I more accurate with irons than a slide mounted optic?

"what typically doesn't work is trying to get the perfect still sight picture and then real quick pull the trigger before it goes away."
I may have been doing exactly that, at 25 yds offhand the dot movement on the target seemed extreme compared to the iron sight, even though it’s the same for both.
