These three :

109003
109203
109303

I looked at the spec sheets but couldn't figure out the differences. I am thinking it is either the trigger, mag safety or internal lock, but I really haven't a clue. I am wanting a 40c with the Novak Lo-Mount Night sights like my other 3 M&P 40's and a local shop has the 109303 for $475 out the door, $30 cheaper than the other two, and it got me to wondering. He said his distributor didn't list any with Novak NS at the moment. So I ordered it after making sure it didn't have the internal lock, mag safety or the heavy MA compliant trigger.

Now where to find the best deal installed on the Novak NS? Any recommendations on where to send it? Anyone local in DFW I can walk in and out and have them installed?

Thanks in advance

SKU: 109303 - No Mag Safety, No Internal Lock, No Thumb Safety
SKU: 109203 - CA Compliant, Mag Safety
SKU: 109003 - Doesn't say, so probably has some safety or internal lock.

GOG says 109003 has Internal Lock and Magazine Safety. I just bought a 109303 on Friday.

To add to the list, mine is a 109203, mag safety no internal lock. My frame has the lock hole but it has a plug in it. I bought it new about four years ago.

I thought the 303 was the first responder model with three mags....

In the above posts you are using S&W's code #'s. Where can I find the information to decipher them? Thank You very much for any help.
