During a Phone conversation with Bruce several months before his untimely death, he commented that to his knowledge, we were the only holster manufacturer that ever gave him the recognition and credit for the use of his designs.
I realize not everyone's into the history of such things ... but fer thems that are, there ya go!
Most popular holster makers have made (or still do) this design ... not the least of which, the late Lou Alessi (DOJ). Apparently, at some point, Bianchi and/or Galco copied the design and named it "Askins Avenger" ... but I see no evidence of "Askins" on their sites, now ... and only Galco retains the "Avenger" name.
When the USPSA Single-Stack (then provisional) division was first created, I actually competed with my Rafter-S (below) ... albeit, not at a particularly high level (mostly as the holster rode much higher, and closer to the body, than an otherwise "legal" holster, would).
This design lends itself to two things (conducive to USPSA/IDPA) ... the gun is not positioned such that it's embedded into yer side ... at which, not only is presentation a bit quicker ... but it's actually comfortable to wear for more than 5min. If ya look at the holsters popular in USPSA Single-Stack and Production, they're almost all more 'er less Kydex versions of this design (at most, with some degree of drop and/or offset).
As noted, this design, when offered as a carry-holster, rides a bit higher, and closer to the body, than a "competition" holster otherwise would ... lending to its concealment.
And I'd guess that's probly why it ain't necessarily the most popular strong-side carry holster there is ... as most folks believe it don't conceal as well as what I see typically referred to as a "pancake" ... and it may not be. I got reason to believe that's not necessarily the case. But I also got reason to believe, it don't really matter. Ultimately, if ya got a carry permit ... particularly in an "open-carry" state ... and yer holster is OWB ... and ya got a cover-garmet ... yer really comparing slight distortions in how that cover-garment hangs ... somethin' most folks would never notice.
Anyhow, if yer like me, and ya git to where a "pancake" is spendin' more time at home ... with yer gun ... than on yer hip ... history would suggest there's something to this Bruce Nelson design ... and ya might give it a try.
