Respectfully, I would have to say I have different experiences with Pardini as owner of 3 who shoots gallery weekly plus practice. But let me preface my experience with saying I started with a volquartsen, then a bob marvel, and eventually graduated to a pardini and have shot every variation from members of my club (e.g., a volquartsen with $300 Rink grips sure make a difference to the tune of 5-10 points). What we use is a function of our budget, how seriously we take gallery shooting, and at what level we compete. I know a very competitive hobbyist who started gallery shooting with a Pardini 3.5 years ago and reached national championship level this year. Doubt he could've with anything else. Would I love to own a High Standard in my collection? 100% but for fun and history it represents. I would argue that when a product or company seizes to be it is because marketplace and consumers have spoken.
Now to your FTF issues relating to cleaning. Sure, Pardini is a precision machine, but I only clean mine every 1000-1500 rounds. What I notice is that trigger gets a tiny bit heavier, and I will eventually have a couple malfunctions from buildup. No issues in between though whatsoever. groups don't get wider and not FTF. However, that was not the case at the beginning before I figured a couple of things out that eliminated all issues. 1- Pardini and its dealer recommend specific ammunition: SK, Lapua Pistol King, and Aguila Target match (which Aguila discontinued last year to rebrand and double the price). Pardini magazines are too tight for CCI standard. I am not saying one must always pay a premium to shoot gallery. I am saying that cheaper ammo and gun will like get you close but not into high 280's and 290's. 2- And, this applicable to any firearm in any discipline, when you load the 5 rounds in your pardini magazine, turn it upside down, pull the spring tab to relieve spring tension, and let gravity sit the rounds right. Sometimes that first round is just not point up enough. This was a tip from an old-timer in my club and virtually eliminated all my FTF issues.
I don't take gallery shooting that seriously. Just having fun with it. Recently discovered that FN 502 is capable to very tight groups and waiting to see what it can do with a red dot.
