To be clear KT has re worked the PMR30 several times. Kervo says he got an early one. They received a lot of criticism.
So many of their guns have had QC issues, frames cracking, barrel issues, etc. The problems with Keltec run much deeper than their shitty customer service and quality control. Back to their early days as Grendel.
- They are a plastic molding company first, and a gun manufacturer second. Which means when they roll out a bad product, they can just blame it on the fact that they're not a gun manufacturer.. They can also use this excuse when they're limiting production/shipping on high demand guns in order to drive up the price/demand with retailers.
- When their products are not working as intended, or their is a major bug overlooked - their CS department is a nightmare to deal with. The've had issues with their PMRs, KSGs, RFBs, etc. About the only thing they've ever made well is their P9/P11/P3ATs and their Sub carbines and even those are just really shoddy quality when you compare them to similarly priced guns made to compete with Keltec. Like I said, they have a really great R&D team that dreams up some cool shit but the way they execute on it and support is horrendous.
