I bought mine on Gunbroker as well about a year ago. They seem to have gone up since I bought mine, as stated above you never seem to see these go up for sale used.
I am new to this as well. I have had more than of the experienced shooters than have been shooting for years emphasize getting everything to memory. Each time I do a match it sinks home more.
I looked at both before I purchased my PM9, when I looked at cost for Trigger work, checkering PM9 was best deal to me.Never looked back and have not regretted extra cash to get it especially when I shoot it.
I just put a Dawson Precision on mine used the measurement tool on their web site to get my measurements. When I called them this is what they recommended before I ordered, especially on a Tactical Sport.
I have been working on this for months and have been able to do. Just took a class and all emphasis was on front sight not target . To me it easier to keep both eyes open moving to shoot that stopping to close and focus.
Started with an SP01 and had it Cajunized that made a big difference. Picked up a 75B in .40 and did it the same way that gun is fun, got a PCR for EDC. Started shooting some competition so I got rid of my only Polymer which was a Walther PPQ M2 and replaced it with a Tactical Sport which I just got. I enjoy each one I shoot.
I shot a couple of USPA matches locally and an Action Pistol, all fun but I am taking a class in a couple of weeks. This seems like the best approach for me instead of wasting ammo trying to learn.
I did the one day introduction class Ronnie Dodd his head instructor puts on. Did it yesterday, it really is something to do. Will take the three day next, there’s nothing that you can compare it to
I used mine a few times, not sure if it helps or makes me try things that just cause me more issues. I seem to be better concentrating on my results on my own than with this and the app. I have actually improved more not using it.
