U.S. firearms maker Smith & Wesson Holding Corp's quarterly results beat analysts' estimates, but forecast weak third-quarter revenue as it expects demand for firearms to normalize, sending shares down 13 percent in trading after the bell.

For the current quarter, the company expects total sales of $90 million to $95 million, with firearms contributing between $72 million and $76 million.

Analysts are looking at sales of $104.8 million.

Firearms revenue within this range reflects more normalized levels of demand and production versus the spike that we experienced beginning in the third quarter of fiscal 2009, Chief Financial Officer Bill Spengler said in a statement.

Starting last November, Smith & Wesson saw sales rise sharply on fears that the Obama administration would bring in stricter gun-control laws, but so far these fears have not been realized.

For the second quarter ended Oct 31, the Springfield, Massachusetts-based company earned $13.3 million, or 21 cents a share, compared with a loss of $76.2 million, or $1.62 cents a share, a year ago.

Adjusted quarterly profit of 10 cents beat market expectations by a penny.

We continued to capitalize in our second quarter on the strong demand for products in both our firearms and perimeter security businesses, Chief executive Michael Golden said in a statement.

The company, which competes with Sturm Ruger & Co Inc, Glock Inc and Taurus among others, saw firearm sales rise 32 percent during the time.

Revenue rose 49 percent to $108.8 million.

Analysts on average were looking for a profit of 9 cents a share, before items, on revenue of $104.9 million, according to Thomson Reuters I/B/E/S.

Shares of the 157-year-old company, which have more than doubled since January this year, were trading down 12.5 percent at $4.61. They had closed at $5.27 Thursday on Nasdaq. (Reporting by Nivedita Bhattacharjee in Bangalore; Editing by Anil D'Silva)
