If you want to go all in, these pistols are considered to be the very best you can get:
-Steyr Evo10 (mechanical trigger) and Evo10E (electronic trigger)
-Feinwerkbau P8X* (mechanical trigger)
-Pardini K12* (mechanical trigger)
-Morini CM200EI (electronic trigger)
-Walther LP500 (electronic trigger)
-Tesro PA10 (mechanical trigger)
*Feinwerkbau P8X and Pardini K12 may have the best mechanical triggers offered by any brand as of today.
If you want to go a little less all in, these pistols are not the manufacturers' latest models, but they are NOT far behind the very best the manufacturers can offer. The most of us will never be able to notice any difference:
-Steyr LP10** (mechanical trigger) and LP10E (electronic trigger)
-Feinwerkbau P44 (mechanical trigger)
-Pardini K10 (mechanical trigger)
-Morini CM162EI (electronic trigger)
-Walther LP400 (mechanical trigger)
**Holds the mens ISSF 10m air pistol world record, set back in 2009!
If you want something nice, but are on a budget, these pistols will serve you very good. They aren't quite on par with todays very best, but if you don't shot 9 or better on average, you probably won't notice much difference, if any at all:
-Steyr LP1 or LP2 (mechanical trigger)
-Feinwerkbau P30, P34, P40 (mechanical trigger)
-Walther LP200, LP300 (mechanical trigger)
-Hammerli AP20, AP20 Pro (mechanical trigger)
-MatchGuns MGH1 Hybrid (electronic trigger).
Whether you want a mechanical or electronic trigger is a matter of personal taste. I like electronic triggers very much, but I know of several people who don't like them. But be aware there is differences between electronic triggers also. Some use micro switches (e.g. Morini CM162EI) and some use an electronic circuit that breaks (e.g. Steyr). Both methods work well, but makes a difference for the feel of the trigger. People who likes to get a sort of feed back trough the trigger tend to prefer micro switches. I like the circuit breaking route.
