Good start! I can’t say enough about how happy I am with the Holosun 510C by the way. Let us know how your buffer/spring tuning goes.

Agree with @Startingover. Do some googling online, HST in 124 non +p is my preference. Lots of ammo tests out there to do some research on. This stuff has been at or near the top in all types of expansion / penetration performance for many years now. It’s fairly cheap if you buy 50 round boxes off a site like ammoseek.com as well. I run at least a full box through any gun before I carry it.

CZ has the edge in trigger, out of the box no doubt. The Tanfo is easy to fix but that needs to be done. If a lightened slide is a priority? Tanfo has the edge. I don’t know what the magwell options are for the TSO, but the Henning (replaces the tolerable factory one) for the Tanfo is downright stellar.

Current model Limited Elite is on the right, in case you haven’t seen the way they currently look. (magwell and grips are Henning, not factory)

I bet most of the guys in this forum happen to prefer the CZ. FYI the Tanfo Limited Custom is a new gun for 2018 and has that funky blue-green finish that’s either a love it or hate it proposition. They don’t show up with a hardchromed stainless look anymore.

I tried it before I installed @bmiller‘s magwell, and the “beercan grip a long mag and STUFF it” technique really does require a magwell. I fully agree with you.

Grip the magazine like you would grip a hammer, or a beer can. So it’s at a right angle to your forearm and wrist, instead of parallel with the basepad resting in the palm like a pistol. Works very well from a center-of-body magazine pouch worn right up front.

Your first four matches in CO you’ll be a “U.” Assuming you don’t zero those classifiers, you’ll find yourself classified as a CO B class once four valid scores are entered. ...Even if you nearly zeroed a couple, and you’re a 5% B class shooter. ? From there, you begin moving up normally. However, if you bump to M in Limited it’ll drag you up to A in Carry Optics.

I do it all the time. Any marginal or slightly high primers get a careful bump in the press. Done it probably a thousand times, never set one off, not even a Federal. Squeeze. Don’t slam.

Do me a favor: Persuadingly argue that what happened was safe gunhandling. Set the rulebook aside, and tell me this is ideal behavior you’d want your friends and family to want to learn to emulate. Right. It isn’t. He made a mistake that is obvious and simple to correct, and that’s not a big deal. But it shouldn’t be acceptable in a USPSA match where 100% safe gunhandling is the expected standard. This is actually quite easy. DQ for unsafe gunhandling. The list of things which qualify for that is purposefully vague and open-ended. Go check the phrasing carefully. You never know what crazy new unsafe action you’ll see at a match, and to be frank, we’re expected to apply some common sense when acting as ROs. So they gave us room to use our own best judgement. If I put a round into a wall nowhere near a target someday, I’d expect nothing less of the RO who is running me when I commit such an unsafe action.The OP owned up to his mistake, and agrees with that assesment.

Buy a cheap but decent quality lightweight slick-side. We’re not building guns for matches that take place at Camp Perry, here.

Usually it mean a makeup shot. ?

Typo. I’m still using a 13 pound spring!

And you cannot mill a gun as low or as securely with an adapter plate style weapon as with a standard slide. The notch is usually .001” shorter than the length of the optic to provide an interference fit which keeps much of the strain off the screws. And if you are working with a standard slide you can often cut slightly deeper.

The leg at the top of the sear on that side of the gun lifts the firing pin block up and clears the path for the firing pin to strike the primer. (These underlined links / advertisements are getting very annoying...)

@B_RAD you forgot the other side of the slide length difference. You can get 5/8” closer to walls and ports (and thus, to the targets) with a G17! That’s an immense advantage that people frequently overlook. I know I’m always going to set up .675” closer to the target if I can.

Jack of all trades, master of none... I have a multipurpose gun: the Walther Q5 which ships with adapter plates like a Glock MOS. I’ve shot 2 matches in CO with the Q and a DPP optic. If you’re going to be switching back and forth between CO and Production, you need the optic mounted lower than that. Otherwise it messes up your index when your dot is so high above the location of the irons. In order to more easily switch back to my Q5 in Production, I’ve got a 4” PPQ slide on it’s way to a gunsmith to get the dot milled down into the slide. I think I have him convinced to mill it down so low that the underside of the optic becomes the top of the now-exposed firing pin channel.

I agree the single overhead inline fab light left a lot to be desired. I am happiest with the relaoding innovations lighting setup. No worries about adhesives staying stuck, and you have a halo of light around the dies.

Someone is in a big hurry to get to 50 posts.

I stagger-loaded a magazine with my 125gr / Prima-V load at 135pf, and my buddies 3.2TG / 147 FMJ load @ 132 pf. There was no perceptible differene in recoil. Neither of us could tell which round had just gone off. I really don’t think ammo softness is this giant reason to reload like most of us think it is. Yes, all of these reloads are much nicer to shoot than factory... but they’re all closely matched to each other. More than we want to admit, especially when paying a premium for 147s. I loaded 147s for two years. Then 135s for three more. I’ve shot 124/125 ever since, and don’t feel like I’m giving anything up. Even in my 26oz polymer gun... it just doesn’t make much difference. Most guys spend way too much time looking for the magically soft recipe. Instead, focus on tuning your loads for *accuracy.* I currently shoot 137-139 power factor ammo which my Walther Q5 will absolutely drive nails with. Knowing your gun will shoot less than 2” at 25 yards with the ammo you walk to the line with on match day is really helpful to your mental game.

@B_RAD heck I shoot PCC... and still think that for an uprange start, they should have the gun on a table which they stand behind, facing uprange, wrists above shoulders. Should have made it harder than handgun, not easier.

@IHAVEGAS it is required with a titan hammer in many cases. The firing pin block otherwise will drag on the pin, or block it entirely. There’s no advantage to it. It simoly accomodates certain sear/hammer combinations that move the firing pin block less than the original parts did.

@B_RAD so... PCC special snowflake treatment for everyone, then?

If he was looking to place well in Limited shooting minor, he was already in for a rough day.

Open division bump. Hammer back, safety off is asafety violation and thus a DQ, as you said. There’s nothing unsafe about starting cocked on safe, it just doesn’t fit Production division’s rules... poof. You’re shooting in Open. Just like someone with 12rds in a mag or an otherwise illegal gun.
