I just came back from a big match and there was a sponsored shooter there that had one. Very Sweet! Clear glass all the way to the edges and a nice even view on 1x.
Well it depends on stage size and format. Big 3-gun field stages can really take it out of you so 5 or 6 a day is enough.
Pistol only I'd say 10 is about the limit before tired / bad habits start to show up.
I also think that if it's a local club match the R.O. should be pointing out 180 "traps" to new shooters during stage brief and a reminder when they are up. If we want the sport to grow it has to be safe and it has to be fun. Sending a new shooter home is just bad press and can be avoided.
I love my XDM but Glock is still on top due to the amount of aftermarket parts and work being done on them on a large scale. Just about anything you can think of is made for a Glock.
Like all guns it just depends on how far you want to go. Triggers, barrels, guide rods are all great but spend some of the money on training also and it will make a big difference
First identify what you need to work on and focus on that. Most will continue to do what they are good at which really doesn't help at all.
Next break down that need into it's smallest components. Run drills that focus on those components. Spend real time on these drills.
I see a lot of people working on everything at the range. Pick 1 or 2 things and really get after it. Also don't spend more than 2 hours at a time without a break. When you get tired you get sloppy and sloppy teaches bad habits.
I like the SC belt. Don't fall for cheap knock offs. A good belt is needed to keep all your equipment secure.
And as stages are becoming more dynamic, now more than ever you need a good belt.
