Shooting an open class shotgun I a hoot too. With 20 plus rounds of 12ga and a dot you usually have a big grin on your face.

Not sure about the accuracy of the Sig but I just returned from sighting in a new Canik TP9FSx and it as accurate as my CZ SP01 Shadow Target Custom. I shot them both side by side at 20yds and the groups were under 2" offhand with 124gr HP reloads at 130pf.

When I shot tac ops I went with the M3K Stoeger and never had any issues. I opened the loading port for quad loading, installed a Bennelli extractor and spring and did a trigger job on it.

I am still running the factory ignition parts. 2 1/2 lbs and dependable

I installed a STI grip with no problem

I put a STI grip on mine with very minor fitting. The barrel is 5 in.

Have you tried the rounds in other open guns?

I went with the 510c on an Atlas mount. Will shoot it later this week but I can already tell I really like it.

Just mounted a 501c on an Atlas mount. Will get to the range for some practice later this week and will update. Looking thru the 510c is like watching a 75" TV in a small room

Thanks. I was leaning towards the 510c due to the size of the glass. I will go ahead and get an Atlas mount on the way.

Is the optic still robust to allow dumping into buckets for 3gun matches?

I am currently running a 507c on my CO gun and really like the clarity of the dot. It is very easy to pick up. I have a Atibal MRD v2 on my open pistol and have considered buying a 510c for my open pistol. I have noticed several for sale in the classified with a mount and have to wonder if the weight is an issue. I would just change the 507c over to the open gun but I will need to buy another mount and don't want to end up with an extra mount if the 507 is to small for the open pistol.

I have been thinking aboit trying a 507 on my open pistol. I really like it on my CO pistol. Does the size of the glass slow you down.

I am shooting 9mm.
