Kirk Merrington can usually work an R Darne trigger down to a comfortable level, but, R models are never going to have 3 lb triggers. That isn't a bad thing, to me.
If you are critical about trigger pulls on a true, hunting shotgun (I can't understand this perversion, but, that's just me) look into a V model. Or, a P17, which is more likely the gun that Rocketman actually had-most people don't understand Darne grading. That is what seven punch marks on a guns flat usually means, and unscrupulous dealers have convinced more than one stroke they are buying a V model.
The safety lever is reversable, side to side, in the breechblock of an R model Darne (did you ever try that, Miller? Again, you've been told that fact plenty of times) and a guy who ACTUALLY WANTS to use his Darne can usually find something that works, either by switching it around, or working the opening lever, to come up with a usable safety.
If there exists a design of shotgun that is more unforgiving in the area of gunstock fit, I haven't seen it. A Darne must fit you in order for you to use it. With any measure of success, anyway. However, lots of guys seem content to just look at them and enjoy what they have, it seems.
Right, Miller?
Good luck on the prospective purchase, and let us know how it comes out. I can probably get you a set of English instructions if you decide to buy the Darne, camotrky.
Best,
Ted
