I see the opinion that it won't hold up to a lot of use but has anyone actually used one enough to have this prove true? I typically do not like the feel of inexpensive guns but as a result I never buy one and shoot it so I have never given them a chance. I have been looking for a 9mm carbine that is still in production and this is one of the only ones I can find except for a Hi Point and Hi Point looks to be in the same inexpensive class. I don't want an AR platform 9 and the Marlin camp 9 and Beretta 9 carbine don't appear to be made any more.
To me the Keltec looks cheap but I really have no personal experience with it.
