I agree, and believe this is getting out of the 'niche' of small, powerful pocket pistols. The website is touting the XR9-L as a pocket pistol as well, but at just under 6" long, I don't think so. The Shorty is borderline "pocket" to me, but that's just me. On top of that, they decided to go with an accessory rail, of all things. For a pocket pistol? I dunno what the thinking was there. Now, on the other hand, the longer format reduces recoil and the claim is that it will now feel like shooting a .22 LR when using standard pressure loads. Pretty cool if so.
If it were me, I would focus on 'small, light, trigger, and looks' with what he's already developed. It's very comfortable to shoot (unlike my R9) which to me is huge since I'm going to want to keep a carry piece exercised and older rounds cycled out, just for confidence. If only the Shorty only had a slightly longer snout so it didn't look so chopped off, would bring a new 'visual' dimension. So, instead of 5.1", let's say it extends to 5.5" like the P238. The barrel would now be 3.7". Perhaps they're wanting to meet some sales requirements which require a minimum of 4.1" barrel length, like Canada, so hence the birth of the XR9-L?? I'll attach a pic of one I Photochopped some time back.
