Shot one match and had to have one. Went on M3K with no issues, left the spring at 16 in for now and will see if it needs shortening. +5 comes even with the barrel. Shipping was ridiculously fast no confirmation email but was at the door 2 days later. 

Response- Confirmation email is sent as soon as it ships, maybe check spam box. USPS tracking number is put in your order online, UPS tracking will be emailed when package is picked up.
