Having been exposed to both, Dennis is a trapshooter himself. Now, whether or not he's shot enough targets to satisfy you is another subject. I've talked to Dennis plenty of times and have been to his shop to have a cheek piece built and some small lessons, but not a whole stock. And have talked to a only a few people who have had guns built by him. They are not that popular yet in the DC/MD/VA area. There are a few around here but not many. There are way more Kolars here. Even more Silver Seitz and Krieghoffs, but that's neither here nor there. But, not only will Dennis go outside the box, he'll take you to his range, stand over your shoulder and you can break targets until you're satisfied, work out your poi and everything else for 1 or 2 days and probaly more if you want. And even offer instructions if you need them. Now, I know and have shot against way more Kolar owners than DeVault owners. And of those Kolar owners who have had stocks built at their factory, none of them have told me that any part of the fitting process involved range time. Not one. The only thing they did was shoot in a tunnel to make sure the gun shot straight. I asked every one of them if they went to a range and they told me no that they only shot to make sure the gun shot straight. Now, if they lied to me, I can't help that because there is nothing that I can do about it but I'm telling what they told me. I hope this helps with your decision.
