I have had several Bostitch pistols and they have always worked well. Bad weather, a fall, nothing ever stopped her. . This one was a lot heavier than the older versions so I expected it to work just as well. . Regardless, when it fell off my trailer (and fell about 2ft) the top broke and flew all over the place. Now I see a $200 repair bill for a gun that has been used for 2 days. Apparently they don't make them like they used to.
