I picked mine up this morning. Some had posted that theirs was soaked in oil. Luckily, mine was not. The trigger will take a few rounds to get used to. It was a little gritty at first but after dry firing 25-30 times it is much better.
The slide seems much easier to work than the Shield 9mm. I have no problem with it. I do have a problem operating the slide release knob. I think some lube and use will correct that. For a total cost of $180 including transfer fee, it seems like a good deal to me and it is really a comfortable fit in my hand. The range will be be the final test.
