had my first problem with one yesterday .a shooter was using his which we mounted about 5 weeks ago and hasnt had any problem . he was shooting my 5 spot tournament yesterday when all of a sudden he gets a 4 another 4 another 4 and than to misses . hes a high 290 shooter .when he came in i saw that the arm attached to the slide was almost off . i took it apart and theres 2 really small screws holding it on . had to get the second smallest allen wrench i have to try and tighted it up .after about another 15 shots it came loose again . this time i loctited it and its held for over a 100 shots . i left a email with throphy ridge yesterday but havent heard anything . you think for 180 bucks it would be attached a little better .
