Innovative Arms is a good company. Although small, they are not a one man shop. I have been doing business with them since they were a one man shop in early 2007. They have been growing steadily since then. Their product line has grown also. They do not settle on the current design of their products. Every time I stop by to see them, they have something new or have improved on one of their old designs. Their suppressors will stand with the best and surpass the vast majority of other manufacturers in terms of quality and performance. AND, get this, they stand behind their work.
I have shot my Innovative Arms suppressors next to some of the other big name manufacturers and mine have clearly performed better.
I am aware of 5 local law enforcement agencies that have their suppressors. They modify and maintain all of the weapons for a nearby nuclear facility. They have their suppressors in stores from Arizona to Florida and who knows where else.
I am sorry you had a less than pleasant experience when you stopped by their shop. Give them another chance, you won't be dissappointed.
