I was dead set on purchasing the Smith and Wesson M&P AR15-22. When I went into the local gun shop to purchase the S&W, the gun expert introduced me to the Ruger SR22 rifle. In comparing the two, I noticed the S&W was almost like a plastic toy gun where as the SR22 was all aluminium except for the stock and grip. Yes the SR22 is heavy, but it is solid in comparison and I only paid about $70 more than the S&W and walked out of the store with it the same day as opposed to have to wait for it to be registered.
Since the S&W is restricted, all mags have to be pinned to 10 rounds only. Having to reload mags with 10 rounds at a time with such cheap ammo stinks. There are multiple mags available for the SR22. I have purchased 2 25 round mags ($30 ea.) and a speed loader for them ($30). A 110 round drum mag is also available for $110. I use this at the range and later I will be taking it to the cottage with me for target practice. If this was restricted, I would be only allowed to take it to the range.
I have bought many aftermarket 'AR' type accessories (rails, rail acc., mounts, etc.) for this in store at very reasonable prices and from online Canadian distributors i.e. Colonel Mustard, Amazon and Dlask Arms.
In summary, I am a big Smith and Wesson fan, but because of it being restricted, I chose the fun route.
