Great idea. I hope you can market it.
To Mr. Boberg: I was hoping to sign up for price information on your info request page. I've tried to leave this on your website, using the info submission form, but for the past couple of days, each time I've tried, I've been met with "Error 500 - Internal server error. An internal server error has occured! Please try again later."
Based on the size of your pistol, it looks like you may be competing most directly with Kahr, and your timing may be just right. Kahr seems to be ruining their reputation. I recently bought a TP40 because I wanted a flat, compact auto with a 4 inch barrel for off-duty carry (I'm a police detective), and that pistol seemed to fit the bill. Unfortunately, it turned out to be the single most unreliable pistol I have ever owned -- which is a shame, since I bought an MK40 seven years ago and carried as a back up in uniform, that has always been completely reliable. I realize all new autoloaders have a break in period, but when a gun can't fire more than two or three rounds at most without the slide failing to go into battery, that's just unacceptable. The seven round magazine (it also comes with a six rounder) was faulty, and once inserted, could not be removed without extreme force being applied to the magazine release button. I sent it back to the factory, and they serviced and returned it promptly, but unfortunately not throroughly. The failure of the slide to go into battery was still in evidence, only now instead of ever 2nd or 3rd round, it happened about a dozen times in a box of fifty rounds (FMJ rounds, BTW). Worse, however, was the about half a dozen times, the gun went "click" instead of "bang" when I pressed the trigger. The striker was not resetting every time. And this wasn't because I was failing to release the trigger; it happened a couple of times as I changed magazines and my finger was completely off the trigger.
I sent the gun back again, this time for a refund. I bought it for personal defense, and I won't ever carry I gun I can't trust. But I have been hearing a lot about Kahr's malfunctioning excessively lately, especially ones with the polymer frames. The staff at the gun shop where I bought the TP40 said just a week earlier they had to send back one they had sold to an NCIS agent, who was reporting the same sorts of malfunctions as mine. If they continue down this road, they will irretrievably damage their reputation with the gun buying public -- which may be good news for you if you arrive on the market with an alternative. Their misfortune may be your opportunity.
A word of caution, however. I have followed the thread about which one to offer first, the XR9, or the XR9 shorty. I understand you had to get a little innovative in fitting in a recoil spring on the shorty. If there is the slightest unreliability with whatever set up you adopted, I would say market the standard XR9 first, and sort the shorty out later. If you hit the market with a less than perfectly reliable weapon, you may never recover from the bad first impression it will make on buyers. Personally, I'd rather have the standard version anyway.
And if you don't mind a suggestion, may I humbly suggest you take a look at the old Remington Model 51, and try to contour the grip and slide as much like that as possible? Especially the grip, which I think is the most ergonomically perfect grip ever put on a compact pistol. Most guns these days, including the compact ones meant for concealed carry, have slides with a blocky, flat-topped cross section that makes both the gun and the holster work against comfort and concealability. Yes, I realize these guns often are still concealable, but they would be more so, and more comfortable to wear all day if the top of the slide had a rounded off contour like most autos of pre-WWII vintage did.
Anway, that's my 2 cents. Sorry for the length, and I sincerely hope you can make a successful go of this commercially. The majority of autos out there today are just more iterations of Browning's tilting barrel. It's nice to see someone innovating for a change instead of just imitating.
