It is only in the past few years that we have seen "lady specific shotguns"
In my opinion, after being a Coach and instuctor over the last 17 years, "Lady Specific Shotguns" is mostly a marketing ploy. Remember when we were convinced that we had to have ported Bbls?
I have some and I wish I didn't.
How about a "person specific shotgun?"
If you wife has a well developed gun-mount, I would encourage you to seek the assistance of a NSCA qualified coach knowledgeable in gunfitting, prior to making any decision on a gun purchase based on gender specific models.
Maybe because women are the biggest group of new shotgun shooters and there is a market for guns that fit them? As a woman who shoots what you describe as a "lady specific shotgun," ("LASS?") I disagree with you that a LASS is just a gimmick, as do my friends who also shoot one. The LASS I shoot has a shorter distance from stock hand to trigger, narrower throat, and shorter stock. It is a gun 5'6" me could shoot out of the box without having to get the stock cut and fits so well I didn't need to install an aftermarket recoil pad. I think that if you routinely had to shoot a gun that didn't fit you without a couple of hundred dollars worth of additional work, you would appreciate having a gun that takes your physiology into account.
As to "person specific" ("PESS?"), it has been around for years in the traditional shotgun designed for a 5'10" man. But for the non-5"10" guy, Caesar Guerini has already gotten there. CG sells the Summit Compact, which has the exact dimensions as the Syren. Why? Because a bunch of shorter guys liked the Syren but didn't want to shoot a gun with roses on it. So the only difference between the Syren and the Compact is CG switched out roses for birds.
Now I do not doubt that there are manufacturers who are trying to climb on the LASS bandwagon without doing the work. But CG put thought and effort into giving me and my friends a gun we can shoot out of the box, and we appreciate it.
And of course women, in fact any shooter, should try a number of guns before they cough up a significant amount of cash for a gun. Who wants to be disappointed in the fit of their gun? MAJ
