I don't know what language that reply to your question was but here's what my comped topend looks like.
It was my first racegun in the late 80's and I've since moved on to a 38 supercomp Para.
I don't know if you can still get these parts but this was an Ed Brown drop in barrel with a Four Star comp. It worked best with 155 grain LSWC bullets.
You can get a cone comp from Brownells
for $150. and all you'd have to do is have your stock barrel threaded.
It really comes down to what you have in mind with it. If you're just plinking then you don't need a comp. If you're going to compete with it and don't want to spend a lot of money on the gun the EGW cone comp would be the cheapest way to go. Also if you're competing and you're competing against 38 supers then you'll need to really practice your reloads. If you can get really good with your reloads you can really give the 38 supers a run for their money.
