I tried both of these out today and have to say I was very disappointed in both....Although I have no experience with suppressors but my experience today, the suppressor was not that quiet in my opinion. The gun jammed or misfed in such a way that it was stuck in battery and the round would not extract. I had rented the gun from a local range and it appeared to be in good condition. The round came out almost bent. I did not get it out but the range employee extracted it...i was deadset on getting both of these and I was glad i could try them both out before purchasing...saved me about 800 bucks....
