I am not sure what shield I have at this point. I believe it is just called an M&P shield 9. I bought it about 5 years ago and it has 7+1 mag and 8+1 mag. When I go to the smith and wesson site, there seems to be a 2.0 , an ez, a compact, etc.... I didn't realize they have so many pistols that look the same. Do they even make the shield 9 anymore? I am looking to see if there is any real reason to upgrade to a different carry gun. Thanks.
